He said: "You look at the form of Carrick and Anderson and how they have developed - you wouldn't have any fears.
"Rooney and Ronaldo are as good as the players we had in 1999. They play without fear. You want people like that as we did against Juventus in 99."
There have been too many disappointments to go with that triumph for Fergie to even contemplate not reaching Moscow.
He said: "We have had challenges in European football and sometimes we have failed them.
"We have failed in some semi-finals when we should have won - against Bayer Leverkusen and Borussia Dortmund."
Memories of that May night in 99 when they came from 1-0 behind to beat Bayern Munich with two dramatic late goals are sure to flood back.
He said: "Just winning it in the last three minutes was indescribable - it was an amazing thing that happened.
"You don't expect to win it when you go into injury time 1-0 down but it wasn't an accident because we had done it so many times that season.
"But that was a cup final, this is Barcelona's home game.
"They will be well up for it, it will be a terrific game with a lot of good football. If we get a goal, it gives us a massive advantage."
