Porto coach Sergio Conceicao insists their Champions League tie with Chelsea isn't over.

Chelsea won 2-0 last night in the first-leg of their quarterfinal tie.

Conceicao said, "We played a good game. The prospects we have for the second leg are neither more nor less than we had before this game. We believe in what we do and in the group we have.

"It was a strong collective performance, there were two individual mistakes that they scored two goals front.

"We did more to come out with another result. We know that we can reopen the tie, we have to score two goals, we have to score a goal first to reopen the tie and I think we are capable and competent for that happen."
