Fabio Vieira has played down concerns over a foot injury and has insisted he will be back in full training in the next week.
Fans were worried when a picture of the £34million summer signing emerged of him wearing a protective boot on his left-foot.
Vieira, 22, picked up the knock during international duty with Portugal last month, but is now close to returning to training.
The former Porto man has not yet made an appearance for Arsenal during pre-season.
