Barcelona midfielder Deco insists he has nothing to prove to Chelsea or Inter Milan at Euro2008.

Deco is considering offers from both clubs and told Sky Sports: "I do not have to prove anything to anyone.

"I'm here to play for myself and for Portugal. My future is not defined at the moment. It's not right for me to comment. I know Mourinho is a great trainer. He won a lot with Porto and he won a lot for Chelsea, and for sure he will win a lot with Inter."
