Arsenal captain Cesc Fabregas is unsure where his career will take him in the future.

Real Madrid and Barcelona have declared interest in the Spain international.

I don't know," he said, in an interview in Champions magazine. "You can never say never but I feel grateful, wanted, comfortable and important at Arsenal. Some people will never understand if I leave, but you have to feel comfortable with yourself. I've given my all for Arsenal.

"You have to be satisfied with what you do - and all you can do is take the decision that's right for you."
