The French international suffered ligament damage to his left ankle during last weekend’s draw with Manchester City and was initially expected to face between six weeks and two months on the sidelines.
However, Wenger today confirmed that the Gunners will be without the 29 year old defender until the New Year after his operation.
Speaking to Arsenal’s official website, he said:
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.
Debuchy had a bright start to his Arsenal career after playing well at the World Cup and was one of the club’s notable summer signings, but his long-term absence would be a significant blow to the Gunners’ back line.
Chambers will probably continue to fill the void until the French international is cleared to return. The youngster filled in for the Frenchman during Saturday’s 3-0 win over Aston Villa, but it’s unknown whether the rising star is ready for consistent appearances against elite competition at this point in his career.
Hector Bellerin is another option after being handed a debut during last week’s Champions League defeat against Borussia Dortmund, but he too looks very raw. The Gunners will also face some problems on the other side of defence with Nacho Monreal ruled out until mid-October and Kieran Gibbs only recently back from a hamstring injury.
