Arsenal boss Arsene Wenger is unsure if Cesc Fabregas will make their Champions League quarterfinal clash with Barcelona.

Cesc suffered a knee injury in yesterday's 1-1 draw at Birmingham City.

Wenger said: "I don't know medically. We will have to assess that tomorrow. He got tackled at the knee. We tried to take him of at first but after he said he was alright."

Asked if Cesc will miss the Barcelona game, Wenger replied: "I don't know."
