The Real Madrid star, however, has remained one of the most controversial figures of the tournament, surrounded by debates that have split fan bases across the world. Tchouameni’s string of controversies began months before the World Cup kicked off. During his 2022 summer transfer from Monaco to Real Madrid, he was accused of rejecting a more competitive project at Liverpool in favor of a higher salary, drawing widespread criticism from Premier League supporters who labeled him “greedy and unmotivated.” Later, in France’s tense semi-final clash against Morocco, his unpunished handball in the penalty area sparked global outrage, with the Moroccan Football Federation filing an official appeal to FIFA and thousands of fans signing a petition demanding a replay. Unconfirmed reports from French media also claimed Tchouameni had clashed with Mbappe in the Les Bleus dressing room over tactical priority, with rumors suggesting he could be dropped from the starting lineup ahead of the final. None of these off-field distractions affected Tchouameni’s dominant on-field performance, however. Under Didier Deschamps’ tactical setup, Tchouameni took on nearly 80% of France’s central defensive workload, averaging 4.2 interceptions, 3.1 tackles and 91% passing accuracy per match. His relentless coverage of the left half of the midfield eliminated the need for Mbappe to drop back to defend, allowing the forward to stay high up the pitch and focus entirely on counter-attacks and scoring opportunities. Match data shows that 7 of Mbappe’s 11 clear counter-attack chances at the tournament came directly from Tchouameni’s tackles, interceptions or long distribution passes, including the build-up to Mbappe’s second goal in the final against Argentina. Deschamps called Tchouameni “the most irreplaceable player in our World Cup squad” in a post-tournament press conference, while Mbappe dismissed rumors of their rift by sharing a social media post praising Tchouameni as his “most reliable teammate on the pitch.” Real Madrid has since extended Tchouameni’s contract to 2029 with a €1 billion release clause, confirming his status as one of the most valuable young midfielders in world football despite ongoing debates over his controversial moments.
