“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.
