Well don’t bet on it. Manchester United just started the season with a 2-1 loss to Swansea last weekend and it shouldn’t have been that big of a surprise to see a top team fail. Having released 14 players for World Cup duties at the end of last season, some players may still be experiencing fatigue.
Let’s also look at some of the top clubs’ performance in their respective leagues just after the 2010 World Cup:
- Barcelona suffered a shock loss to Hercules in the second game of the league
- Liverpool lost three of their opening five matches although in their defense they played Arsenal, Manchester City and Manchester United
- Udinese lost the opening four matches
- Everton did not win any of their opening five matches
It's not just after noting down these cases that one would start to wonder whether fatigue or lack of preparation could have crept in. In an academic paper published in the Journal of Performance Analysis in Sport during 2011, Lames and Kolbinger prove that German Bundesliga teams who release many players in the summer performed badly during the first half of the 2010/11 season. Whereas 'teams with few or no releases performed surprisingly well'.
I have looked at teams that released the most World Cup players during 2010 for a brief back-of-the-envelope test. The table below compares the number of the number of points obtained in the first five league games in the 2010/11 season to the number of points obtained in the first and last five league games of the preceding 2009/10 season. For example, Barcelona lost one of the first five league games just following the 2010 World Cup that was won by a Spanish team with a core of their players. This is a worse outcome (marked ‘-’) than their impeccable 2009/10 league record during which they won the first and last five league matches.
|Early 2010/11 compared to|
|Team||Players||Early 2009/10||Late 2009/10|
+ denotes the team did better in early 2010/11 than the other periods during previous season.
Bucking the trend, Arsenal managed to obtain points from all matches in their opening five league matches of 2010/11 by winning three and drawing two. This compared favourably to losing two and three games in their first and last five matches respectively of the preceding season (‘+’). Nonetheless it can be noticed that for every team that performed better after releasing players, there are about two that performed worse.
At the end of last season, twenty one teams released at least seven players to participate in the World Cup. Together with the teams mentioned in the introduction one can add the expected Chelsea, Liverpool, Manchester City, PSG, Arsenal, Atletico Madrid, Porto and Zenit St Petersburg (in order of released players). These teams may have the quality reserves to still obtain good results, even if similar teams such as Barcelona, Internazionale and Panathinaikos missed a step or two just after the 2010 World Cup and we’ve just seen Manchester United do the same.
Yet I fear this time round that Juventus, Napoli, Internazionale, AC Milan, Lazio, Dynamo Moscow, Borussia Dortmund, Vfl Wolfsburg and Schalke 04 may be more liable to a ‘surprise’ bad run given their starting eleven dependency on World Cup released players and the smaller gap with competing teams.
Note: The number of released players relates to the end of the season just preceding the World Cup (2009/10 and 2013/14). Player transfers may have affected the clubs’ number of released players. For example Portsmouth had sold off most of their team at the end of the 2009/10 season after their relegation from the English Premier League.
