Mbappé Knee Alarm Bells Ring Again Ahead of Benfica Clash

Kylian Mbappé’s dodgy left knee is back in the headlines — and Real Madrid’s Champions League hopes are once again being held hostage by it.

What’s happened?

According to French outlet L’Équipe, Mbappé cut Tuesday’s training session short and is now considered a serious doubt — if not a definite absentee — for Wednesday’s Champions League play-off second leg against Benfica at the Bernabéu. He was sent for medical tests the same afternoon, which is never a great sign, is it.

Madrid made it even more obvious something was up by not releasing their squad list the night before the game, holding off until matchday itself. That kind of thing doesn’t happen when everyone’s fit and dandy.

The same old story

This isn’t new territory. The knee problem originally kicked off after a knock against Celta back on 7 December, and a scan before the new year confirmed ligament damage that should’ve kept him out for at least three weeks. Instead, he was back after just 11 days — the pressure of the Supercopa final against Barça in Jeddah playing a massive part in that decision.

Since then, it’s been a relentless schedule with barely any breathing room. In the space of roughly a month, Mbappé only had one game off — against Real Sociedad. That’s not a recovery plan, that’s just hoping for the best.

The situation is starting to feel a lot like the Manchester City match earlier this season, where he was kept on the bench as a precaution and Madrid ended up losing 2-1. Could be déjà vu all over again.

The bigger picture

Before the news broke, Álvaro Arbeloa had been speaking Mbappé up in his pre-match press conference, making a point of highlighting the Frenchman’s commitment and how much he contributes even when not fully fit. Reading between the lines, that’s basically an admission that he’s been playing through pain since December — and that every time he steps on the pitch, it’s a bit of a gamble.

• The injury is to the external lateral ligament of the left knee
• He returned 11 days early from what should’ve been a 3-week layoff
• He’s had barely any rest since, with only one match off in over a month

What happens next?

This is where it gets properly interesting. The debate has shifted from purely medical to strategic. Sources at Valdebebas are apparently suggesting that — whether he plays against Benfica or not — Mbappé needs at least 10 days of proper rest. Fixtures against Getafe and a trip to Vigo are being floated as games Madrid could afford to sacrifice to give him that window.

And looming large over all of this? The 2026 World Cup. Mbappé won’t want to be limping into the summer tournament that represents arguably the biggest prize left on his personal wishlist. At some point, the sums just don’t add up if you keep running him into the ground.

Madrid have a massive call to make — and they’ve been kicking it down the road for two months already.
