Arsene Wenger has revealed that Laurent Koscielny is a concern after suffering a head injury in Arsenal’s Premier League clash against Southampton on Saturday.

The Gunners face a tie against French giants PSG in the Champions League on Tuesday, but they could be without their 31-year-old central defender.

The France international suffered a blow to the head in the match against the south coast side, with the contact being made close to his eye.

The defender’s eye immediately swelled up with Wenger admitting that Koscielny is a concern for his side.

“Yeah. He will be a little concern. It’s already very swollen,” said Wenger to the Daily Mail.

Arsenal are already without senior defender Per Mertesacker following a knee injury, but Koscielny’s injury isn’t as serious and may only see him miss one match.

The Gunners added Germany international defender Shkodran Mustafi to their side in a £35million move from Valencia this summer as well as youngster Rob Holding from Bolton for £2million.

They also sent young defender Calum Chambers out on loan to Premier League rivals Middlesbrough in an attempt to give the 21-year-old some much needed first team experience.

The Gunners have kept one clean sheet in their opening four Premier League matches after a 0-0 draw against champions Leicester.

They will be hoping that the addition of Mustafi can improve their side as they look to continue their reign in England’s top four.
