The fretting over Arsenal's squad depth was supposed to end when the Premier League's summer transfer window closed on Friday.

Raheem Sterling's last-gasp arrival on loan from Chelsea had many Gunners supporters pitching up at Emirates Stadium on Saturday enthused by the options manager Mikel Arteta has at his disposal. Yet they left the ground after Saturday's 1-1 draw with Brighton & Hove Albion concerned about a midfield area that suddenly looks light ahead of the biggest week of the season by some distance.

First, there is an international break in which to draw breath and regain some of the composure that Arsenal temporarily lost here following Declan Rice's 50th-minute red card. But then comes a seven-day period in which they travel to Tottenham Hotspur for the north London derby, Italy for a Champions League opener against last season's Europa League winners Atalanta and then to Premier League champions Manchester City.
