The twice World Player of the Year has been troubled by tendinitis problems all season but made his first start for Internazionale in two months in the 2-2 draw with city rivals Milan on Saturday night.
"I may not have the match rhythm back yet, but I'm ready to give everything to beat Manchester," said the Brazilian yesterday, who played just the first half of the derby. "Last night's game wasn't a test. It was a real match. It was difficult but I did my duty. I'm pleased with my performance, I'm gradually getting better and I don't feel any pain any more.
"The team are playing well at the moment and we're creating a lot of chances. We're also preparing very carefully for the match against Manchester, who are a great side, and are very quick on the break.
"I'm hoping to play for the whole match. It will be difficult to do so, but I'm not ruling it out. I'm certain I can go out there and do my job well. I'm convinced that the rest of the team are going to do the same. They are very, very motivated.
"This is going to be the most important match of our season. Our pride is at stake and we must show that we are up to the mark. I'm sure both sides will have chances to score, and also that it will be a great game - possibly with a lot of goals. We have to accept they might score - we've conceded goals in all of our recent games.
"My presence alone won't be enough - we all have to do better because they won't be frightened, not of me, or of any other player."
