AGONY ... Cesc after penalty
"It is the fibula. I think I put my leg between Puyol's when I was fouled, and kicked it.
"I don't think it is going to be good news. For 85 minutes it was not a gamble to play. I knew in my mind I was not 100 per cent and I knew in my mind there was something there.
"But until the penalty I was feeling quiet good. It was a gamble worth taking, it was an amazing experience, an amazing game and I will remember it all my life."
An initial scan straight after the game proved inconclusive.

For the penalty, Fabregas was then fouled by Carles Puyol, who was sent off, before firing the ball into the net.
Fabregas insisted: "The team can definitely do it without me. Barcelona have lost big players like Puyol and Pique so I don't think it is the same without them.
"We will see but it will be tough and I think that we can make it. I think this is the best team I have faced in my life. Theo made such a difference, he created a lot of problems and I think he was the best player."
