"Always as a manager, you must be confident your team can win, and any Liverpool team will always be confident," said the Spaniard.
"But we know Chelsea are a very good team. In the last five years, they have spent big money on players and they have a very good squad.
"They may not accept what happened here two years ago, but they cannot change things now.
"They are very difficult team to play against. What we will do now is concentrate on the Premier League and then we will concentrate on Chelsea.
"But they will be tough. They have spent money for five years, they are in other semi-finals and chasing trophies, that is what they want and have prepared for.
"Yes, we only have one trophy to go for, but they would not want to change what they are doing now."
