Liverpool's record signing Alexander Isak is once again on the sidelines, having recently been forced off with a groin issue in the UEFA Champions League.
This latest knock immediately reignites the long-running debate surrounding the Swedish striker: is Isak injury-prone, and does his patchy fitness record justify the Premier League record fee Liverpool paid to acquire him from Newcastle United this past summer?
A detailed look at Isak's availability since joining Newcastle United in 2022 suggests that, despite his undeniable world-class quality when fit, fitness concerns remain the single biggest red flag in his career profile.
The alarming number of games missed
Data tracking shows that since the start of the 2022/23 season, Isak has missed approximately 55 games for club and country due to injury, with muscular problems repeatedly striking at crucial moments.
Alexander Isak’s injury history (Since 2022/23)
| Season | Days Missed (Approx.) | Number of Injuries/Absences | Key Injury Type |
| 2025/26 (Current) | 15 days (to date) | 1 | Groin |
| 2024/25 | 43 days | 3 | Hamstring, Broken Toe |
| 2023/24 | 56 days | 2 | Groin (Twice) |
| 2022/23 | 107 days | 1 | Thigh problems (Long-term) |
The recurrence of groin and thigh issues, muscle injuries that often plague players returning from fitness deficits, is particularly concerning for Liverpool, especially following a disrupted pre-season.

The fitness balancing act for Arne Slot
Liverpool Head Coach Arne Slot acknowledged the difficulty in managing the striker's return following a protracted transfer saga that saw Isak miss crucial preparation time.

Following the Champions League win over Eintracht Frankfurt, where Isak was substituted at half-time, Slot commented on the difficult balance: “We thought he was well prepared for that, but the margins at the top are small.
"I'm hoping it won’t be that bad, because if he’s out for a few weeks, it will put him back.”
The manager's previous caution in building Isak's minutes, which saw the forward playing only limited time to regain "match sharpness," appears to have been undone by this latest setback.
The physical profile of the tall, lean striker is often cited by experts as increasing his susceptibility to muscle strains, making careful management crucial for Liverpool’s long-term investment.
