Speaking about the possibility of the double, he said: "It is a big opportunity to do it.
"We've spoken with the players and we know that it will not be easy.
"All this season has been very hard, with many difficulties, but having got to this stage, we want to do our best to use this opportunity.
"We lost the opening game even though we were much better than Fenerbahce but the players want, like everyone at the club, to be in the semi-final.
"The first match was one of our good performances with the worst result.
"Fenerbahce are a good team. They know how to play good football and had a good result against us.
"We expect a very difficult game against a very good team."
