Arsenal face an anxious wait to discover whether or not a swollen cheekbone will sideline Laurent Koscielny for the Champions League clash with PSG on Tuesday.
The French international suffered the blow to his face in the win over Southampton on Saturday, and required treatment for several minutes before the Gunners eventually secured a 2-1 victory.
However, the knock has put his participation against the Ligue 1 champions in doubt as Arsene Wenger could be forced to throw summer signing Rob Holding into the deep end.
Fellow summer arrival Shkodran Mustafi will play alongside either teammate, but with Per Mertesacker and Gabriel already sidelined with injury, Wenger can ill-afford to be without his most experienced and consistent defender for such an important game.
He may have no choice in the matter though, with Holding on alert as he looks to win his place in the starting line-up back after featuring in the opening games of the season despite only making his Bolton Wanderers debut just over a year ago.
The 20-year-old did well in the circumstances, but it will undoubtedly be a major boost for Arsenal if Koscielny is passed fit and can take his place in the team at the Parc des Princes on Tuesday night.
Wenger’s side have now secured back-to-back wins in the Premier League, and they will be hoping to take that momentum into Europe against a PSG side struggling for form.
The French giants are seventh in Ligue 1 after four games, picking up two wins, a draw and a defeat so far as they deal with their reshuffle over the summer which saw Laurent Blanc and Zlatan Ibrahimovic leave the club.
