Milan take a commanding 2-0 lead into the second leg in the Camp Nou, with Ambrosini key to their win last night.
“It was a game we had to play like this,” explained Ambrosini.
“We were very careful and allowed Barça very little. It is only the first half of the tie, as going there thinking we’ve done something definitive would be a terrible mistake.
“It was a great achievement, but we have to consider the 180 minutes. We’ll enjoy this evening, then think about the derby [at the weekend with Inter].”
