Referring to last season's semifinal, Ancelotti said: "We didn't play with courage and personality, which are fundamental aspects in this kind of game. We lacked that in the second leg. There was obviously also a lack of football in some situations during the game.
"It wasn't just a mental problem, but also a technical one. They put a lot of pressure on us up front and we didn't find alternative solutions. We want to avoid these things in this tie."
Ancelotti also said: "Yes, very nervous. On a personal level, the hours before a match are a time when you have to suffer. I was thinking the other day that defeat is suffering and victory is happiness, but it's not that way. Victory is relief.
"It's happiness if you win trophies, but an isolated victory is a relief. You're calmer and happier the days after, but suffering is part of your job. It's what keeps you alive. It's fuel for me."
