Arsenal were given a big boost ahead of Sunday’s Premier League clash against Everton with defender Laurent Koscielny returning to training.

As reported by the Express, the Gunners centre-back has been suffering from an Achilles injury which has limited his game time in recent weeks, but a final decision on any potential selection is expected to be made on matchday. Manager Arsene Wenger revealed on Arsenal’s official website that there was a slim chance of Koscielny featuring if scans were positive this weekend.

“We have an uncertainty over whether Koscielny will be available or not. He will have tests (this weekend) and then I will make the decision,” he said. The French international has been key at the heart of the Arsenal defence this season and the London club will want to give him minutes to boost his match fitness ahead of next Saturday’s FA Cup final.

Koscielny, 31, has made 32 Premier League appearances this season, scoring two goals. He played a full 90 minutes in last Saturday’s 4-1 win against Stoke City but missed Tuesday’s 2-0 win against Sunderland. Wenger won’t want to risk a serious injury by playing him but will be keen to have the former Lorient man fit to start in the FA Cup final alongside Rob Holding and Shkodran Mustafi.

Should he play against Everton, he could do his teammate Alexis Sanchez a favour in the race for the Premier League Golden Boot by keeping Everton striker Romelu Lukaku quiet at the Emirates Stadium.
