Arsenal's Mathieu Debuchy out for three months following ankle surgery

Arsenal right-back Mathieu Debuchy has been ruled out for three months after undergoing surgery on the ankle he injured against Manchester City.

The Frenchman was stretchered off nine minutes from time at The Emirates after damaging ligaments in his left ankle when landing awkwardly following a header.

The 29-year-old, who represented his country in this summer’s World Cup finals, was playing only his fourth Premier League match for the Gunners since moving from Newcastle in July for £12million.

Arsenal manager Arsene Wenger admitted: "He has had surgery and will be out for three months.

"A reasonable delay is three months. It all went well but it can be a week or two earlier, or a week or two later, but it will be around three months.

"It is a blow, of course, how big it will be we will only know afterwards because it will be down to how well we replace him. We bought (Calum) Chambers for that."
