AC Milan's Massimo Ambrosini: 'Barcelona tie stands at 50-50'

AC Milan midfielder Massimo Ambrosini believes that their Champions League last-16 tie against Barcelona "stands at 50-50".

The Italian champions will head into the second leg at Camp Nou on Tuesday 2-0 ahead from the first leg played at the San Siro last month.

"We have so much to lose but also so much to win," he told UEFA.com. "We are in a positive situation, but in my opinion this tie still stands at 50-50.

"Last year we beat Arsenal 4-0 yet we were still close to being knocked out. We have players with a lot of experience, but I also know it won't be easy for our younger players, although the experience will do them good.

"Honestly, I don't think what happened against Arsenal will happen tomorrow. We don't see the match any other way than to play it with a knife held with our teeth."

Striker Giampaolo Pazzini will miss the match due to injury, while defender Philippe Mexes is doubtful with a thigh problem.
