Roma coach Rudi Garcia describeS Barcelona as "one of the greatest teams in the world" ahead of their UEFA Champions League Group E match at the Nou Camp on Tuesday and called on his team to "make an entrance".

SOUNDBITE: (Italian) Rudi Garcia, Roma manager:

"Barca only need a draw to end up first in the group. As for ourselves losing or drawing doesn't change things for us. Even though if we draw at this stadium it will be a great result and a great psychological boost for us. But if we want to depend on ourselves it is fair to say we must win here. We need to make an entrance, even though so few teams have been able to achieve that during the past year. Because we know Barcelona is one of the greatest teams in the world."

SOUNDBITE: (Italian) Rudi Garcia , Roma manager:

"We didn't need to see the last test of Barcelona in Madrid to realise they are a terrific squad. All of their players in any position have a great level and also they have a great coach. And now we are at their home stadium in such a mythical stadium. The game played in Madrid didn't change at all the way we see this team."
