Tomas Rosicky has been left 'devastated' after he picked up a thigh injury that could keep him out for at least a month.

The Arsenal midfielder was making his first appearance of the season in the FA Cup win over Burnley on Saturday, when his injury jinx struck again.

The Gunners do not know the full extent of the damage just yet and are waiting for scan results to confirm the situation, but it looks as though the 36-year-old is set for another spell on the treatment table.

"He's devastated. Unbelievable," boss Arsene Wenger said. "Nobody understands [how he got injured]. 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 top-level, technically.

"He told me after the game that he did it straight away, then I understood why that happened to him. He said: 'I stayed on, because you couldn't change anymore.'"

Rosicky's contract is up at the end of the season and there is now a real chance he could have played his last game in an Arsenal shirt.
