According to reports, Real Madrid medical staff performed an MRI scan on the wrong leg of Kylian Mbappé back in December, leading to a misdiagnosis of his knee injury as a sprain. The proper scan on December 31 revealed a partial posterior knee ligament tear, but Mbappé continued playing despite varying levels of pain. The incident has raised questions about the club's handling of the star player's injury.

What they’re saying

“I had reached a stage where I didn't know what was wrong with me. I didn't go through that period in the best way. I wasn't the happiest player in the world. But I'm happy now because it's truly behind me. It's all gone.”

— Kylian Mbappé

“This story makes no sense and, if true, actually makes Mbappé look just as bad. Doctors usually confirm the injury site multiple times before placing a large knee coil over the injured knee during an MRI. If the wrong knee was scanned, that means the doctor messed up, and Mbappé was so checked out that he didn't realize they put the device on his uninjured knee.”
