Real Madrid forward Kylian Mbappe has been sidelined with a muscle injury, sparking concerns about his availability for the upcoming derby against Atletico Madrid this weekend.

The La Liga club announced on Wednesday that Mbappe suffered an injury to the biceps femoris in his left leg.

The French international, who joined Real Madrid from Paris Saint-Germain earlier this year, has had an impressive start, scoring seven goals in nine appearances across all competitions.

His remarkable form was cut short when he was substituted in the 80th minute of Madrid’s thrilling 3-2 victory over Deportivo Alaves on Tuesday night.

Eyewitnesses noted that Mbappe appeared to gesture towards his thigh as he left the pitch, prompting immediate concern from fans and staff alike.

Following a series of tests conducted by Real Madrid’s medical team, the club announced the details of his injury and stated that Mbappe’s recovery will be closely monitored.

Spanish media outlets are reporting that he is likely to miss the highly anticipated clash against Atletico, a match that could significantly impact the LaLiga title race.

As it stands, Real Madrid is positioned second in the league with 17 points, trailing leaders Barcelona, who have a game in hand and play against second-bottom Getafe later Wednesday.
