Arsenal midfielder Cesc Fabregas insists he has not suffered a hamstring injury.
"I felt my hamstring in the first half," he said. "I kept going, but I felt it again in the second half. I just came off to prevent something. It's the first time in my life I have felt this and I didn't want to take a risk. I'd say I'll be fit for Saturday, but the doctors are always trying to be a little bit careful. We will see the reaction.
"It's hard losing. We want to win, but you will not win all your life. One day you have to lose. We have lost against a good side and that's it. We will try to come back and win on Saturday. We have three important games and the league is the most important thing now for us."
