Arsenal have been handed another major injury blow as Arsene Wenger revealed that goalkeeper David Ospina will be out for up to three months with a thigh injury.

Ospina only joined the club this summer after starring for Colombia at the World Cup, but with Wojciech Sczcesny suspended after a red card against Galatasaray, Arsenal will have to turn to young Emiliano Martinez for the Champions League game against Anderlecht on Wednesday.

"It is exactly the same (injury). He had his first injury in Nice, it was a knee problem and I think he was a bit rushed back," Wenger told a news conference.

"He didn't use his legs so his muscle became weaker, then he got injured during the World Cup. And after that he came to us injured, from the World Cup. It took him two months to play a game.
