MADRID: Real Madrid star Kylian Mbappe is set to play his biggest game against Barcelona on his return. Earlier on Tuesday, the French superstar had to leave the pitch during the match against Alaves due to discomfort. Meanwhile, Real Madrid beat Alaves 3-2. Coach Carlo Ancelotti called it a “knock” in the post-match presentation. “Mbappe asked for a change to avoid any problems,” he said. With that in mind, Marca revealed observations about the French professional player on Thursday. After tests carried out by Real Madrid’s medical services today, Mbappe has been diagnosed with a biceps femoris injury in his left leg. The French superstar is expected to be out for three weeks, ESPN reported, citing sources, leading him to miss the matches with Lille in the Champions League and Villarreal in La Liga and the international break with France. Despite the injury, the French captain is still not ready to damage his ambitions. It’s worth noting that this comes amid confirmation that the former Paris Saint-Germain stalwart is set to return. According to Marcy, Mbappe is expected to return against Celta Vigo on October 19. However, the French star’s main goal is to be fully fit for the big clash with Barcelona on October 26 – the most important match of the first season of El Clasica at the Santiago Bernabeu.
