Arsenal boss Arsene Wenger may be without Cesc Fabregas for up to three weeks due to a hamstring problem.

Fabregas was substituted during the Gunners' 4-1 home win against Portsmouth, with speculation mounting that the midfield maestro could miss the showdowns against Celtic, Manchester United and Manchester City.

Speaking in the aftermath of the game, Wenger revealed that the Spanish club captain felt it was 'not too bad.'

"He has a hamstring problem," said Wenger. "I think he will be short for Wednesday, certainly."

"He is not definitely out, he thinks it is not [too bad]. If it is a little pull he will be out for three weeks, if it is just tightness maybe he can get away for Wednesday. But we will see. In 48 hours we will have a better view."
