Weekly Post number 191 of the CIES Football Observatory presents turnover strategies followed in domestic league matches of the 2016/17 season by clubs from 27 top division European leagues. Chelsea FC holds the record for the highest percentage of minutes played by the 11 most employed footballers: 85.5%. Conversely, Manchester United is among the 50 clubs with the highest turnover rate.

Many Champions League participants are part of the 50 clubs in which the 11 most fielded footballers played for the highest percentage of minutes: Tottenham, Napoli, Sporting Clube de Portugal, Monaco and Atlético Madrid. Europa League finalist Ajax also features in the list. This finding shows that it is possible to be successful both at domestic and European level without high turnover rates.

However, Manchester United followed a radically different strategy. José Mourinho’s team is among the 50 teams in the 27 leagues surveyed with the lowest percentage of minutes played by the 11 most fielded footballers: 62.8%. This reflects an unusually high level of changes in line-ups selected. In the future, more stability is probably needed to sustainably improve results.

Issue number 190 of the CIES Football Observatory Weekly Post ranks footballers from the five major European leagues according to the number of minutes played in official games since July 1st 2016. The French and Atlético Madrid star Antoine Griezmann tops the table ahead of Wilfred Ndidi (Genk, Leicester and Nigeria) and teammate Koke.

Apart from Griezmann, Ndidi and Koke, five other footballers played for more than 5,000 minutes: Danijel Subaši? (Monaco and Croatia), Kamil Glik (Monaco and Poland), Neymar (Barcelona and Brazil), Paul Pogba (Manchester United and France), as well as Marquinhos (Paris St-Germain and Brazil).

In the top 100 positions of the rankings are ten players of the two Champions League finalist teams: five from Juventus (Higuaín, Buffon, Bonucci, Mandžuki? and Khedira) and five from Real Madrid (Kroos, Ronaldo, Ramos, Marcelo and Navas). While some fatigue certainly exists, it should not prevent players from producing an enjoyable show on Saturday.

Issue number 189 of the CIES Football Observatory Weekly Post ranks big-5 league players according to their tackling skills. The tackling index is calculated by multiplying the average number of tackles attempted per 90 minutes and their success rate. Only players fielded for at least 1,500 domestic league minutes are included in the analysis.

Players from three different championships figure in the top three positions of the rankings: Valentin Rongier (Nantes), Carlos Casemiro (Real Madrid) and Idrissa Gueye (Everton). The top ranked Bundesliga player is Douglas Santos (Hamburg), while Gastón Brugman (Pescara) tops the Italian Serie A table.

In quantitative terms, the big-5 league who player who attempted the most tackles is Sergio Álvarez (Sporting Gijón): 138. Idrissa Gueye (Everton) achieved the most: 99. The highest success rate among players in the top 100 list was recorded for Pedro Obiang (West Ham): 89%. A successful tackle is defined by our data provider OptaPro as tackles resulting in winning possession or the ball being put out of play.

Issue number 188 of the Weekly Post presents the best players of the 2016/17 big-5 league season. The rankings were elaborated according to the exclusive CIES Football Observatory’s approach to measure player performance on an objective and comparable basis. Lionel Messi outranks Cristiano Ronaldo in the table for wingers.

Three Bayern Munich players top the rankings in their respective position: Manuel Neuer for goalkeepers, Javi Martínez for centre backs (ahead of teammate Mats Hummels), as well as Thiago Alcântara for central defensive midfielders. Only footballers who have played at least 2,000 minutes in domestic league games are included in the analysis.

Alex Sandro and Marcelo (full backs), Kevin de Bruyne (central attacking midfielders), Lionel Messi (wingers) and Dries Mertens (centre forwards) head the rankings for the other positions considered. Except for de Bruyne and Marcelo, all these players are also to be found in the CIES Football Observatory’s 4-3-3 best XI of the season alongside Bruno Peres (right full back), Paul Pogba and Naby Keita (box-to-box midfielders), as well as Cristiano Ronaldo (left winger).

The ability to both create and convert big chances is a key success factor. However, issue number 187 of the CIES Football Observatory Weekly Post highlights that in four out of the five major European leagues, teams heading the table distinguished themselves from runner-up clubs above all for their ability to score with no clear-cut opportunity available.

Rome (26), Paris St-Germain (25), Tottenham (34) and RB Leipzig (25) scored significantly fewer goals from situations with no big chance available than Juventus (37), Monaco (36), Chelsea (41) and Bayern Munich (40). In no big-5 European league, the club having created the most clear-cut scoring opportunities tops the rankings: PSG, Barcelona, Rome, Borussia Dortmund and Manchester City.

The key question is thus to know why some teams scored more goals with no big chance available. Luck certainly plays a role at this level. However, the greater desire to win should probably also be taken into account. In addition, while the best form of defence is attack, we should not forget the importance of defensive teamwork to win trophies.
