AC Milan captain Ambrosini: So much to lose and so much to gain
Milan go to Spain defending a 2-0 aggregate lead.
"We have so much to lose and so much to gain," he told a Press conference. "We have players with a lot of experience in Serie A, and it's only right we pass on that knowledge.
"Barcelona will take hold of this game, but our main weapon is the counter-attack.
"We have the grit between our teeth and are ready for any situation."
