Arsenal manager Arsene Wenger has expressed his sympathy with veteran midfielder Tomas Rosicky following his latest injury setback.

The Czech Republic midfielder suffered a thigh injury in the FA Cup win over Burnley on the weekend in what was his first appearance of the season for the Gunners.

The 35-year-old is in the last year of his contract and is expected to depart from the club in the summer, indicating he may have played his last game in an Arsenal shirt if he is unable to swiftly return from his latest problem.

When asked about the reason behind Rosicky's latest injury, Wenger said: "Nobody understands. I told him straight away after half-time to warm up.

"I observed him, he's very conscientious Tomas, he did sprint and sprint, and sprint. He comes on; after three minutes he got the injury.

"I looked at him and thought: 'Tomas you do not run properly' because he didn't lift his legs and he lost some balls. I was amazed because he is at the top level technically. He told me after the game that he did it [the injury] straight away.

"He warmed up well, for 20 minutes. He's devastated.

"Unbelievable. He's such a good player but his career has been disrupted by so many injuries. He was born in 1980, he's 35, it's difficult for him. Let's hope we have good news, that it is not as bad as feared."
