Barca managed to get a draw from the first leg in France.
“Barcelona are greater favourites than ever,” he declared.
“We missed the second goal that would have given the Barcelona side real doubt.”
He added: “[I still believe] but I try to be realistic.
“We played against what is considered to be the best team in Europe. At this level, we must try to be up front and score whenever we are given the chance. Tonight we had those chances but missed the finishing touch. That’s why we deserved only to draw.”
