AC Milan captain Massimo Ambrosini knows how hard it will be to keep his team's 2-0 first leg advantage in tact at Camp Nou tomorrow night. The 37-year-old veteran says that he and his team mates respect Barça, adding that they have learned a valuable lesson in last meeting's with Arsenal and don't want to suffer a similar experience this time around against Barcelona.

Barça: "They are a very strong side with a clear identity. They will try to control possession - they have so much quality and class that they can do that. But we're ready for them".

Keeping Leo Messi at bay: "Messi could quite easily score two goals tomorrow but even if he does, we only need to score one, so it won't matter. We need to score to be on the safe side and feel relaxed".

Milan's objective: "It would be fantastic not to concede any and to score at least one. The key will be confronting the match with the right attitude - that's what our coach has been drilling into us during the past few days".

Barça dominated the first leg: "We didn't read what the Spanish press had to say about the first leg. It has no influence on us. We'll do our talking after the game".

Past experiences: "We have a lot to lose tomorrow. We are in a good position. We have a decent lead but that doesn't guarantee anything. Last season, after beating Arsenal 4-0 in the first leg, we were nearly eliminated in the return. That something we should learn from".

Young squad: "Playing at a stadium like Camp Nou is special. We have played who are building up experience in Serie A but if you really want to become a great player, then you have to pass tests like the one we have against Barça tomorrow night".
