Hitzfeld said: “It’s a very big disappointment.
“We got a 2-2 draw in Milan and we had great hope that we would advance. But we always knew that Milan can win away from home.
“We were unlucky not to score first. It may have been different then.
“They got a lot of confidence from those two goals and they have great players. We tried everything and we went out fighting, but Milan was clearly the better team.”
