Emirates Stadium side out suffered injury during Man City clash.
Arsenal boss Arsene Wenger has confirmed that French full-back Mathieu Debuchy is set for three months out on the sidelines following surgery on an injured ankle.
“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.”
The French international suffered his injury during Arsenal’s 2-2 draw with Man City the weekend before last and the former Newcastle United man was replaced by youngster Calum Chambers for the club’s 3-0 win over Aston Villa on Saturday.
Arsenal signed Debuchy in July in a £12m deal following the departure of Bacary Sagna to Man City, with youngster Carl Jenkinson moving to West Ham on a season long loan deal.
