Real Madrid forward Kylian Mbappe has been diagnosed with a thigh injury and is expected to be sidelined for three weeks, missing key fixtures including the derby against Atletico Madrid and a Champions League match against Lille. Mbappe, who has scored seven goals in nine matches this season, sustained the injury during Madrid's 3-2 win over Deportivo Alaves, where he was substituted in the 80th minute. Coach Carlo Ancelotti mentioned that Mbappe requested the substitution to avoid further problems. The injury adds to Madrid's ongoing injury issues, although Eduardo Camavinga is expected to return to training. Real Madrid currently sits second in LaLiga, trailing Barcelona by one point.
