Arsenal manager Arsene Wenger has confirmed defender Laurent Koscielny will be out of action until December after undergoing surgery on his Achilles.
The France international missed Sunday’s 5-0 win over Burnley in the Premier League after picking up the injury during the Europa League semi-final defeat to Atletico Madrid last week.
Koscielny went down inside the first 10 minutes and was stretchered off, with France then ruling him out of their World Cup campaign.
He had been hoping to play his part at the tournament in Russia this summer but is instead out for months.
Wenger told reporters: “Koscielny is, of course, devastated because he needs surgery.
That means he will be out for six months. You will not see him until at the beginning of December at best.”
As well as Koscielny, Wenger will be without midfielder Santi Cazorla for the last two games of the season.
The Spaniard has been out injured since October 2016 with an ankle problem and Wenger admits he may have played his last game for the club, with his contract up in the summer.
He added: “It’s a shame. I brought him here and I love the player and the person. He looks quite good, prepares well, runs well, but medically it’s too much of a risk to rush him back.”
Arsenal take on Leicester in their next league game and they are 2.00 to win at the King Power Stadium. Leicester are 3.60, with the draw also 3.60.
