Arsenal boss Arsene Wenger admits he's desperate to have Cesc Fabregas fit for today's clash with top four rivals Aston Villa.

Fabregas' participation against the visitors, who have won all of their last four and are unbeaten in seven league games, is in doubt due to a hamstring problem.

The Spain international has been missing since the December 16 draw at Burnley and withdrew from training on Thursday due to the problem.

"There is still an uncertainty about him," said Wenger.

"He was supposed to practice on Christmas Eve but he still had some pain in his leg.

"We did not get him out so we still don't know if he will be available for the squad or not. It is 50-50.

"He is a very influential player and a great player too so I want him to be with us."
