According to Guillermo Rai and Mario Cortegana of The Athletic, Real Madrid's medical staff performed an MRI on Mbappé's wrong leg in Dec. 2025. The 27-year-old was experiencing issues with his left knee, although the scan was performed on his right leg.

As the World Cup looms, France star Kylian Mbappé says his left knee that bothered him for weeks is now fine. The Real Madrid striker was used as a substitute in his team’s last two matches as he works his way back into form and has joined his France teammates ahead of a couple of friendlies in the United States this week.
