Liverpool FC - Form, expectations, decline and recovery

Liverpool have been difficult to judge so far this season. They have a new young manager in Brendan Rodgers who is trying to transform their style of play. But the transfer window left them woefully short of attacking options, and this has been exacerbated by the injury to Borini, one of the few attacking players they did manage to bring in. They've also lost one of their best midfielders, Lucas, for a long period with a thigh injury, and have been reliant on the excellent form of youngsters such as Raheem Sterling and Andre Wisdom to fill gaps in a thin looking squad.

All of this has made it difficult to tell whether they are a team on the up, or one destined for mid-table obscurity (or worse), and opinions tend to reflect people's opinion on Rodgers and whether they believe in what he's trying to implement - so some fans will point to 8 games unbeaten before Spurs in midweek as being a good solid run to build on, while others point out that the same run included only 1 win in 5.

Regardless, their next run of six games consists of Southampton (H), West Ham (A), Aston Villa (H), Fulham (H), Stoke (A), QPR (A). Six games that they will consider to be 'winnable', and which will go a long way to defining their season. A good run would put them back in contention for the European places with the teams around them faltering. So, let's look at how good the recent form looks in comparison with their form over the last few years, and what they might realistically expect from the next six games.

The chart below shows the number of points gained from the last 6 league games, going back to 08/09 when Benitez was in charge, and shows form up to and including Swansea away last Sunday.



All managers and teams have good runs and bad runs at some point, and this is reflected in the chart. Even Roy Hodgson managed to achieve 13 points from 6 games at some point in his otherwise disastrous tenure. Rodgers appears to have presided over the worst run of 6 games, however this is slightly misleading as it includes the end of season defeat to Swansea under Dalglish. The recent run of 9 points from 6 games seems to be roughly par for the course over the last two years.

It is interesting to note that since Benitez no-one has managed to achieve 15+ points from 6 games, and Dalglish only achieved 14 points once. It is also worth noting that the last time Liverpool managed to gain 11+ points from 6 games was at the end of 2011. As such, whilst the run of games coming up looks relatively easy in Premiership standards, and fans might be expecting 12 points or more, 10 points would seem to be a good return based on 2012 form.

The last 6 form guide is not an ideal measure however. At the start of this season Liverpool played Arsenal, Manchester City and Manchester United in their first 6 games, and the points return in part reflected the toughness of this run of games. It can be more useful to look at form over an extended time period, so the chart below shows results over the previous 19 games, again going back to 08/09 under Benitez.



Here Liverpool's decline in recent seasons can be clearly seen. Their form peaked under Benitez with 46 points from 19 games  during 2009, clear title winning form. As has been well documented, the club began to unravel financially during 09/10, with the owners Hicks and Gillett struggling to finance the huge debts that they'd placed on the club. Xabi Alonso was sold to Real Madrid, replaced by Alberto Aquilani seemingly because Liverpool were able to pay the transfer fee entirely in instalments.  Glen Johnson was also signed from Portsmouth because they still owed Liverpool £7 million for Peter Crouch and so the up front cost was reduced. These deals were a sign of things to come and the club was reportedly 'a day away from administration' before the takeover by Fenway Sports Group in late 2010.

The impact on the team's form is clear to see. From title winning form in 2009, they slipped to finish 7th in 2009/10. Benitez was sacked, and his replacement Roy Hodgson presided over a spell where Liverpool spent some time in the relegation zone, and he eventually left in January 2011 having gained just 24 points from the previous 19 games.

There was a brief revival under Dalglish, with top-four form of over 35 points from 19 games towards the end of the 2010/11 season. But, the decline during 2011/12 is shown starkly in the chart. When Dalglish left the club, Liverpool had secured just 18 points from the previous 19 games. Of course, during that period Liverpool also reached two cup finals, winning one of them, but the league form was atrocious, and was that of a side which would get relegated if replicated over a full season.

So, Rodgers inherited a side that was in relegation form, and in that context the recent form appears to be a bit of a mini revival. Liverpool fans won't get carried away, as it's still not great and is a long way from where they want to be. If the next 6 games provide 10 points or more though, as the fans will hope and even expect, then Rodgers will have gone some way to restoring Liverpool's league form to a level which will allow them to compete for the European places once again.

Most Competitive Premiership Season Since 1996-97!

As expected (see previous blog post at http://sporteconomist.blogspot.com/2011/04/most-competitive-english-premier-league.html), this year’s premiership proved to be one of the most competitive seasons since the competition began. The previous post showed that the season was on course to be the most competitive since 1997-98. In the end it went one better, being the most competitive season since 1996-97 and the third most competitive season since the premierships came into being in 1992-93.

The chart below shows the competitive level of the premiership since its inception in 1992-93. Building on the analysis of footballeconomics.com I’ve created a competitiveness index, which is equal to one minus the standard deviation of the proportion of points achieved by each team. This is a statistical technique which allows us to analyse the variation in the league. A perfectly competitive league would produce a competitive value of 1, as all teams would end up winning an equal proportion of the points on offer.

(click on chart to enlarge)


As can be seen from the chart, the long term trend has been for a decline in the competitiveness of the premier league ever since its inception, but this season has bucked the trend. 

In 2004-05, Liverpool finished 37 points off the leaders, qualified for Europe in 5th place, and won the European Cup. This season Birmingham and Blackpool finished 41 points off the leaders and were relegated. So tight was the spread of points this season that just a couple of wins in a row could make a huge difference to a team’s season. Just 8 weeks ago, Aston Villa fans were unfurling a banner calling for Gerard Houllier to be sacked as they almost fell into a relegation battle. In the end they finished a creditable 9th in the league. Roy Hodgson’s Liverpool occupied the relegation places for some of the season, only for Kenny Dalglish’s Liverpool to finish in 6th place, one place better than Rafa Benitez achieved last season. Meanwhile, many were rightly praising the performance of Owen Coyle’s Bolton Wanderers as they were riding high in the table earlier in the season, but they eventually ended up in 14th place. For all these reasons and more, many football pundits have argued that this season was the most exciting and competitive league for a long time, and it’s interesting to see that the stats above endorse this view.

There are reasons to be optimistic, e.g. with the new UEFA financial fair play rules, that this year’s increased competitiveness may be a sign of things to come, and if so we can look forward to a much more competitive league in future years. At the top of the table, the top four seems to be moving towards a top six, with Liverpool strengthening, and Spurs proving that last season’s fourth place was no fluke with a fifth placed finish this time. Similarly, looking at the teams coming up from the Championship, there are no obvious whipping boys next year, and the battle against relegation is likely to be as fierce as ever.  Time will tell whether this turns out to be true, or whether like 2003-04 (itself the most competitive for 8 years at the time) this is just a short term blip in the long term decline

On the eve of the finals night of the 2011 Premier League Darts season, let’s take a brief look back on the 14 nights of competition that have brought us to this point. There are some interesting quirks in the statistics along the way, not least the fact that the individual with the highest 3 dart average in any single match this season (Mark Webster) has finished rock bottom of the league. It may also provide some pointers for who might beat the seemingly unstoppable Phil ‘The Power’ Taylor at Wembley Arena on Thursday night (Live on Sky Sports).

The stats shown in the table above are a testament to the remarkable consistency that ‘The Power’ has shown in this season’s premier league, after the disappointment of the World Championships. The only player to achieve a 3-dart average of 100+ over the 14 nights of the season, he also lost 28 fewer legs than his nearest rival, and won 7 more against the throw.

Looking at maximums, it’s interesting that Raymond van Barneveld finished second in the final league table, and second bottom in the total number of 180s thrown during the 14 nights of the season. There’s a saying in golf “Drive for show, putt for dough”, i.e. a good drive might look flashy but it’s how well you finish each hole that wins you the money. This table seemingly illustrates that darts is similar – 180s might look impressive, and get the crowd on their feet, but on their own they won't win you matches.

3 dart average – best performances

Looking at the season as a whole, the three highest 3-dart averages achieved in individual matches were:

110.19   -              Mark Webster vs Adrian Lewis in Week 4

109.36   -              Phil Taylor vs James Wade in Week 13

107.93   -              Simon Whitlock vs Raymond van Barneveld in week 9

It’s interesting to see that Mark Webster, in such terrific form in week 4 against Adrian Lewis, fell to pieces afterwards and ultimately ended with the lowest three-dart average of all the players, despite being the only player to average over 110 in any individual match.

It’s also worth highlighting that further down the list Phil Taylor occupies 6 of the top 10 places in terms of the highest 3 dart averages in individual matches, again underlining his dominance of this year’s season so far.

Checkout percentages

There are some missing stats in relation to checkouts on Planet Darts, but from the available statistics, the following are the highest checkout percentages achieved by players in individual matches this season:

80%        -              Mark Webster vs Adrian Lewis in week 4

73%        -              Adrian Lewis vs Simon Whitlock in week 5

73%        -              Adrian Lewis vs Mark Webster in week 8

73%        -              Terry Jenkins vs Mark Webster in week 12

Again, Mark Webster comes top with that awesome performance in week 4. He’s also been on the receiving end of two of the next  best checkout performances though, which depending how you look at it may highlight how well opponents played against him in some of his losing matches, or the lack of pressure that he was able to put them under.

Interestingly, Phil Taylor has just one place in the top 10 checkout percentage performances (6th for his 57% against Adrian Lewis in week 11), while Adrian Lewis has 4. Phil Taylor occupies all of the next 5 positions though (places 11-15) showing that he has been remarkably consistent in taking his chances this season, despite others having more clinical individual matches.

Will anyone beat Phil Taylor to the title?

The stats suggest that it’s unlikely. Taylor’s 3 dart average for the whole season is within a point of the best one-off achieved by Anderson and Lewis, and within 2 points of Van Barneveld’s. His average checkout percentage (at 48%) is as high as anyone else in the league too - only Lewis matches him - and of the four finalists only Lewis has had a better night this season in terms of checkouts (73% on his best night compared with Taylor’s 57%).

In short, looking purely at the stats from the 14 weeks of the Premier League so far, if Phil Taylor has an average night tomorrow night then it will probably be good enough to beat the best that the other three players have demonstrated so far this season in the Premier League. For anyone else to win the title will require them to be at their very best, and for Phil Taylor to be slightly below par.

You can never say never in darts though, and upsets are always a possibility. Looking at the stats, despite finishing last of the four qualifiers, Adrian Lewis might have the best chance of providing that upset. He's the only guy to beat Phil Taylor in this year's premier league, as the reigning world champion he shouldn’t be intimidated by the occasion, and the stats so far show that he is likely to match Phil Taylor in terms of checkouts IF he’s able to score well enough to give himself the opportunity to take them...
