Despite losing the first-leg 2-0, Porto boss Sergio Conceicao has warned Chelsea that it isn’t over just yet.
Conceicao also claims Porto did enough to win the game and Chelsea only scored through mistakes made by Porto players.
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 from.
“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.”
