Barca are 2-1 up from the 1st leg two weeks' ago.
Brazilian Ronaldinho is quoted as saying: I'm sure Barcelona will reach the quarter-finals.
"Having seen Chelsea close up I am still 100 per cent confident that we will go through to the quarter-final.
"Chelsea gave us a hard game but our performance deserved better. We have a better team and I'm certain we will score at Stamford Bridge."
Samuel Eto'o then got in on the act by declaring: "All we need is one goal, then that will be it and we will have struck gold.
"That will be enough to see us through and I intend to score it."
Eto'o added: "(Scoring) would be a massive revenge for me after the way I was treated by Chelsea. I will make them pay for not buying me.
"Mourinho will be forced to regret it."
Barca skipper then popped up with these pearls of wisdom: "There's no area of Chelsea's attack where they're better than our defence.
"But we can't play defensive football on the back foot like Chelsea.
"Barca don't believe in closing down the entertainment value and sitting back and hoping for your opponents to make an error.
"Chelsea have two styles of play which are to sit back and close off a game or play route one football.
"This is a game for our great stars to show up in and we will go out to win the game because that's our style."
