Arsene Wenger has confirmed that Mathieu Debuchy has had surgery on his left ankle and will be out for approximately three months.

The France international sustained the injury after falling awkwardly during the 2-2 draw with Manchester City at Emirates Stadium.

Once the injury had an initial period to settle, an assessment with a specialist on Friday confirmed the need for an operation and the 29-year-old was treated straight away.

“He has had surgery and will be out for three months,” Wenger told Arsenal.com. “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.”
