Arteta believes that Arsenal striker Trosad will be able to catch up with the new Premier League season that will start next week.
The Belgian international missed Arsenal's 3-0 victory over Athletic Bilbao. Three players were suspected of playing before the game, but Havertz and Calafiori both passed the health assessment. This means Trosad has not made a debut since he suffered a groin injury against Tottenham last month in the North London Derby warm-up match.
However, Arteta is optimistic about the prospect of the player's Premier League opening match against Manchester United. He said: "I think he will recover in a few days. His groin is a little uncomfortable, but it should be fine."
