"In that respect it is going to be hard but we have the players who can make us successful. They are confident about expressing themselves and they enjoy playing.
"They are not afraid of challenges and there is enough youth in the team to make them ambitious and want to get there.
"This is probably my best squad ever in terms of completeness."
The United boss added: "The one thing these lads have is the quality to play on the big occasion. In that sense, it is like 1999.
"They are very confident - Nani, Ronaldo, Anderson, Rooney. It gives you hope they can handle big occasions like that.
"You want to see them express themselves and be fearless. I am not slightly worried about their temperament."
