Using technical data collected by our partners Wyscout, the CIES Football Observatory has developed various synthetic indices on a base of 100 to measure the level of performance of players in six areas of the game (more details here). This Weekly Post presents the hundred U23 midfielders from 46 leagues around the world with the highest values in ground defence (see below).

Borussia Mönchengladbach’s Rocco Reitz has the highest score. The German is ahead of another big-5 league player, Barcelona’s Spaniard Marc Casadó, and Genk’s Guinean Ibrahima Sory Bangoura. After a season in the reserve team, Bangoura is emerging as a potential transfer candidate to an even bigger club. Two other players from outside the big-5 are in the top 10: Amine Lachkar (Willem II) and Nick Fichtinger (Zwolle).

Tenth overall, Las Palmas’ Portuguese Dário Essugo (on loan from Sporting CP) has the highest score among players who have not yet celebrated their twentieth birthday. The three youngest players in the top 100 are Frenchmen Ayyoub Bouaddi (LOSC Lille) and Warren Zaïre-Emery (Paris St-Germain), as well as Swede Lucas Bergvall (Tottenham). Of the 46 leagues analysed, 32 are represented by at least one player in the top 100.

The ground defence index is calculated by adding up the defensive duels won by players below elbow height, pass interceptions and anticipations on loose balls (without clear possession) in relation to the average values measured at team and position level (on a pro rata basis of the different positions played). The value obtained is corrected by the success rate of ground duels undertaken and the sporting level of the matches played.

The 491st CIES Football Observatory Weekly Post presents the U25 players who are sportingly the most deserving for a senior national team debut. The rankings were established on the basis of a performance index* specifically designed by our research team using Wyscout data. They include the ten players with the highest performance scores from 50 nations around the world.

For the major nations, the following U25 non-full international footballers are considered the most deserving: Santiago Hezze (Olympiacos, Argentina), Jarne Steuckers (Genk, Belgium), Murillo (Nottingham Forest, Brazil), Elliot Anderson (Nottingham Forest, England), Hugo Ekitike (Eintracht Francort, France), Nico González (Manchester City, Spain), Yann Aurel Bisseck (Inter, Germany) and Marco Carnesecchi (Atalanta, Italy).

For all the players listed, the Post also presents the estimated transfer value according to the CIES Football Observatory’s statistical model, based on the assumption of an international debut. In this case, the five highest values were recorded for Jamie Gittens (England, €74.2m), Désiré Doué (France, €62.9m), Santiago Castro (Argentina, €60.5m), Archie Gray (England, €56.6m) and Dean Huijsen (Spain, €51.2 m)

* The index is based on the footballers’ playing time over the last year, the sporting level of the matches played and the players’ performances in six areas of the game (method here).

In the last two transfer windows, only one team has had a negative net spending* of more than €250 million: Brighton & Hove. Now firmly established in the Premier League, the English club recorded a deficit of €197 million during last summer and €56 million this winter. Premier League newly-promoted Ipswich Town and Saudi Arabia’s Al-Nassr round out the podium of the teams with the worst balance sheets. All the data is available free of charge here.

In the other European big-5 leagues, the biggest deficits were recorded by Atlético Madrid (-€116m) in Spain, AS Roma (-€111m) in Italy and Bayern Munich (-€63m) in Germany. Manchester City totalled the biggest win last summer (+€157m) and the greatest loss in the transfer window that has just ended (-€226m). In terms of spending, Brighton & Hove (€317m) are ahead of Chelsea (€310m) and Manchester City (€278m).

An English club tops the list also in terms of the most positive results: Leeds United (+€132m). Another team relegated from the Premier League with a squad featuring many young players highly rated on the transfer market ranks in the top three: Burnley FC (+€101m). RC Lens is second (+€106m), while Benfica (+€92m) and Porto (+€82m) are just off the podium.

* All figures include any add-ons regardless of their effective payment or receipt, as well as fees earned from sell-ons. Loans with a non-conditional obligation to buy have also been considered.

Issue number 489 of the CIES Football Observatory Weekly Post forecasts the results up to the end of the season of teams in 42 leagues around the world according to their performance level. The latter was measured on the basis of a statistical model including the number and location of the passes and shots made and conceded so far by teams (Wyscout data), regardless of the results obtained.

In the five major European leagues, the best progress in terms of points per match should come from Toulouse and Monaco in Ligue 1 (with Auxerre and Strasbourg at the opposite end), Borussia Dortmund in the Bundesliga (RB Leipzig at the opposite), Cagliari and Como in Serie A (Empoli at the opposite), Tottenham and Manchester City in the Premier League (Newcastle at the opposite), as well as Girona and Getafe in La Liga (Leganés at the opposite).

Across all leagues, the greatest positive gaps between the points per match achieved so far and those predicted up until the season end were measured for Bulgaria’s CSKA Sofia (+0.66), United Arab Emirates’ Al-Wasl FC (+0.54) and Cyprus’ APOEL FC (+0.5). Conversely, Serbia’s FK Mladost (-0.62), the Emiratis of Ittihad Kalba (-0.52) and Saudi Arabia’s Al-Riyadh SC (also -0.52) are expected to experience the biggest drops in form.
