Kylian Mbappe, the star striker for Real Madrid, is a doubt for the highly anticipated El Clasico on May 10 due to a thigh injury. The club confirmed that he has sustained an injury to the semitendinosus muscle in his left leg after he was forced to leave the pitch during a 1-1 draw against Real Betis in La Liga last Friday. Initially, Real Madrid indicated that Mbappe was suffering from a muscular overload, but subsequent tests revealed a more serious injury. With Madrid currently 11 points behind leaders Barcelona in the league table, they face Espanyol on Sunday before the crucial match against Barcelona. If Real Madrid drops points against Espanyol and Barcelona secures a win against Osasuna, they will be crowned champions for the second consecutive season. Mbappe's injury is particularly concerning as he has already dealt with injuries this season, including a knee issue that sidelined him for two months. With the World Cup set to begin on June 11 in the United States, Canada, and Mexico, his fitness will be closely monitored.
