Arsenal management are worried about the future of Thomas Partey.

Partey's frequent fitness issues are a growing concern for the Gunners, says The Sun.

The Ghana midfielder missed the final nine games of last season as Arsenal fell apart and lost out on a top-four finish to Spurs right at the death.

He has already missed half of their eight matches this season with a persistent thigh problem and has just returned early from international duty after complaining of discomfort in his knee.

Arsenal are hopeful that his latest injury is not serious but are not taking any risks ahead of Saturday's crucial North London derby.
