Cesc Fabregas believes the experienced Milan midfield can "kill you in a minute" if you are not careful.
The 20-year-old admits he is in admiration of some of the players he will come up against on Wednesday night when the Champions League holders visit Emirates Stadium.
It has been billed as a game between old and young with the Italians being seen as the veterans. However, speaking at Tuesday's pre-match press conference, Fabregas was respectful of his elders while remaining confident his side would come through.
"Yes they've been playing a long time together, and have more experience than us," he said. "But we have quality and we really want to do it. That's very important at the same time.
"We have to be careful because of the experience they have. They can kill us in a minute.
"I really like Pirlo to be honest. He's a great player, very intelligent and a great passer of a ball. He's always looking at the best solution. There's also Kaka, who had a great year last year, and we'll have to be careful of him.
"They have many strengths not just those two. They have players who work hard for the team and they're one of the best midfields in Europe.
"But we've been meeting clubs like Milan in recent
years - Juventus, Real Madrid - and we know we can do it. However
we'll have to be at our best."
