Benitez said: "My priority is to win against Aston Villa now, enjoy today, and it will be a question of time if we can play at this level and win games it will be easier.
"When you go to a semi-final any team will be difficult. Swansea is a good team who try to play football, and because we are so close to the final their motivation will be there.
"The first thing I have to do is beat Swansea, but to win trophies is important for any manager. First we must concentrate on the semi-final and after that we can talk about the semi-final."
