Arsenal chiefs believe Hector Bellerin's highly-publicised vegan diet is cause for his injury problems.

Bellerin spent nearly nine months out after rupturing the anterior cruciate ligament in his left knee against Chelsea back in January 2019.

The Spaniard is still enduring fitness problems now as he battles a groin tear, which he has having to take painkillers to play through the pain of.

The Athletic reports there are fears among some staff members at the Emirates that his diet may not be giving him the best chance of returning to his best performance level.

Bellerin has enjoyed promoting himself as a vegan and has been since 2016.

The Spain international has endured fitness problems in recent seasons though and there are those within the Arsenal set-up who are questioning Bellerin's choices.
