The 93rd CIES Football Observatory Monthly Report analyses the high-pressure data produced exclusively by the French company SkillCorner. It notably reveals the link between the frequency with which players are subjected to high intensity pressure from opponents, the position they occupy on the pitch and the style of play of their team.

During the 2023 and 2023/24 seasons, outfield players from teams in the 28 leagues studied experienced an average of 9.2 instances of high-intensity pressure per match. The highest values were measured for dominant teams: Manchester City (15.2 pressures per game), Bayer Leverkusen (13.9) and Columbus Crew (13.5). Manchester City also tops the table for the percentage of ball retention under high pressure (84.2%), followed by Real Madrid (81.2%) and Paris St-Germain (80.8%).

The study also highlights the players who stand out most positively in terms of ball retention under high pressure, based on the residuals of a statistical model that takes into account their position and their team’s style of play. This approach is particularly useful for scouting purposes to target recruits with an unexploited potential.

The 455th CIES Football Observatory Weekly Post ranks teams from 54 leagues around the world according to their shooting efficiency. The latter was measured from the residuals of a statistical model explaining 78% of the differences in goals scored per team (not including penalties) on the basis of three variables produced by Wyscout: the number of expected goals according to the dangerousness of the chances created (also not including penalties), the number of shots on target and in total.

With 0.69 more non-penalty goals than expected per game, Greece’s PAOK FC have the most positive gap in absolute terms, reflecting judicious shooting decisions, as well as particularly effective finishing. Portugal’s Sporting CP (+0.59) and Italy’s AS Roma (+0.52) complete the podium. The Italians outrank Inter and Arsenal in the five major European leagues, followed by Bayern Munich, Bayer Leverkusen and Valencia.

In terms of the most negative gaps, with 0.63 fewer goals than expected per game, Melbourne City top the list, ahead of four particularly inefficient big-5 league teams: OGC Nice (-0.56), Olympique Lyonnais (-0.49), Rayo Vallecano (-0.48) and Montpellier (-0.47). Everton and Köln are the least effective clubs in the other leagues of the European big-5, Go Ahead Eagles in the Dutch Eredivisie, Vizela and Benfica in the Portuguese Primeira Liga, as well as RSC Charleroi in the Belgian Pro League.

The 454th CIES Football Observatory Weekly Post presents the 20 outfield players for six positions playing in 28 leagues around the world whose number of accelerations* per match (SkillCorner data) deviates most positively from the value expected with respect to their position and their team’s style of play (level of possession, pressure and verticality), according to a statistical model explaining more than half of the differences observed between players.

With 1.93 more accelerations per game than expected, Victor Osimhen (Napoli) ranks first among centre forwards. The Nigerian is ahead of Ghanaian Emmanuel Boateng (Rio Ave) and Ivorian Vakoun Bayo (Watford). Among the wingers, the podium is made up of Álvaro García (Rayo Vallecano), Armand Laurienté (Sassuolo) and Felipe Anderson (Lazio). Dutchman Guus Til (PSV Eindhoven) tops the list for attacking midfielders.

As for the other positions, Sessi D’Almeida (Pau) is ahead of Josh Laurent (Stoke City) and 19-year-old Ezechiel Banzuzi (OH Leuven) among central or defensive midfielders; Jeremie Frimpong (Bayer Leverkusen) crushes the competition for wing or full backs with the greatest positive gap overall (x2.1 compared to the expected value) ahead of Marlon Fossey (Standard Liège); Danilo (Juventus), Ruan (Sassuolo) and Davinson (Galatasaray) make up the top three among centre backs.

* Accelerations refer to runs of at least 0.7 seconds at >10.8 km/h/s. Only footballers who played at least 1,000 domestic league minutes in the current or last completed season, of which more than three quarters in the same position, are included in the rankings.

Issue number 453 of the CIES Football Observatory Weekly Post analyses the StatsPerform and Wyscout data on the number of cards, fouls and injury time measured over the last year for 71 leagues around the world. The study shows major differences between leagues in terms of all the indicators taken into account, reflecting different ways of interpreting the game by both players and referees.

In terms of red cards, the values range from 0.61 per match in Bolivia to 0.10 in the Japanese J2. For yellow cards, the extremes were measured in Uruguay (6.07) and, again, in the Japanese J2 (2.73). As for fouls, the maximum was recorded in the Brazilian Serie B (30.3 per match), while the minimum was observed in Norway and the Netherlands (20.0 in both cases). In terms of extra time, the data ranges from almost 14’ in Qatar and Saudi Arabia to 6’ in Finland and Slovakia.

If we relate the number of fouls to yellow cards (second yellow included), the values stretch from about one card every four fouls in Chile to one every eight in Japan. Among the European big-5 leagues, this ratio is much higher in the French Ligue 1 (6.8) than anywhere else (around 5), which may reflect either a lower propensity to hand out cards or a greater tendency on the part of referees to whistle for ‘small’ fouls.

The 92nd CIES Football Observatory Monthly Report analyses from a spatial perspective the origin of the >€75 billion transfer revenues collected by clubs worldwide between 2014 and 2023. Overall, clubs have generated around two-thirds of their transfer incomes from international deals. However, this proportion varies greatly from country to country, with a minimum of 37% for English clubs and a maximum of 73% for French teams among the big-5 league associations.

Teams from only three countries other than England - among the twenty whose clubs generated the most transfer incomes during the last decade - collected less money from foreign teams than from domestic ones: China (22%), Mexico (44%) and Italy (48%). The dependence on foreign transfers is much greater for clubs in associations such as Portugal (91%), the Netherlands (90%), Belgium (87%), Brazil (86%), Argentina (83%) or Turkey (77%).

For many countries, England is the main fund provider for international transfers. Among the nine other associations whose clubs received the most indemnities between 2014 and 2023, this is notably the case for the Netherlands (38% of total transfer revenues were generated from England), France (32%), Germany (31%), Spain (30%), Portugal (30%), Belgium (25%) and Italy (14%). Brazil (Spain) and Argentina (Italy) are the only exceptions.

Number 452 of the CIES Football Observatory Weekly Post presents the 169 clubs in the world whose volume of incoming or outgoing player transactions over the last five seasons exceeded the €100 million threshold, as well as their net spending for the last ten, the last five and the last season. In terms of the volume of money exchanged, Chelsea is clearly in the lead with €2.572 billion, followed by Manchester City (€1.726) and Paris St-Germain (€1.404).

In total, 14 teams from seven countries have ’shuffled’ over a billion euros in five seasons: five from England, two from Spain, two from Germany, two from Italy, one from France, one from Portugal and one from the Netherlands. Twenty-four countries, including five outside Europe, are represented among the 169 teams whose volume of transactions exceeded €100 million, with a maximum of 30 clubs for England.

In terms of balance sheets, the values for the current season range from -€384m for Al-Hilal to +€167m for Southampton. Over the last five seasons, the figures stretch from -€782m for Chelsea to +€354m for Benfica. Finally, over the last decade, the values go from -€1.348bn for Manchester United (with only Chelsea also totalling a >€1bn deficit) to +€732m for Benfica. All the sums presented include any add-ons, regardless of their effective payment.
