Isak's deformed knee

Alexander Isak became the focus of debate when images of his unusually shaped knee went viral on social media, raising concerns about his increasingly alarming fitness level.

Isak's knee has an unusual deformity.

Many Liverpool fans are disappointed by the Swedish striker's persistent injury problems. One commenter sarcastically remarked that Isak is "a player as fragile as glass," talented enough to make a difference but too delicate to maintain consistent fitness throughout the season.

In fact, Isak's injury history has become a major problem for Liverpool. Since moving to the Premier League in 2022, the former Real Sociedad striker has consistently suffered from muscle, hamstring, and groin issues.

The 2025/26 season saw Isak's worst period, as he was sidelined for over 150 days due to a fractured fibula and a series of groin and adductor muscle injuries. In the 2024/25 season, the striker also missed over a month due to toe, hamstring, and groin injuries.

A similar situation persisted for many years. In the 2023/24 season, Isak was sidelined for nearly two months due to a recurring groin injury. In his first season at Newcastle, he was also forced to sit out 107 days due to a thigh problem. Even further back, during his time at Sociedad, the Swedish striker frequently struggled with ankle and hamstring issues.

When in top form, Isak remains one of the most dangerous strikers in the Premier League. But for Liverpool, the biggest concern right now is no longer the Swedish striker's class, but how long he can maintain his fitness.

Despite his high transfer fee, Isak has made limited contributions and is considered one of the worst new signings this season.
