Inter Milan hero Marco Materazzi insists they're capable of upsetting Liverpool tonight.

Inter host the first-leg of the round 16 tie at San Siro stadium.

“Playing with the Inter jersey in the Champions League is the best thing, as San Siro transforms in games of this calibre," said Materazzi.

“We really need that atmosphere! It'll be fundamental not to show weakness in the first leg, because Liverpool are deadly on the counter-attack.

“Liverpool are perhaps the toughest opponents Inter could've drawn, but I do not forget what happened against Chelsea in the Round of 16 in 2010.

“I remember we faced them in a pre-season friendly in Pasadena and when we were drawn against them, I thought, how can we beat this lot? They seemed to be on another level.

“However, we were the ones who then qualified! It's not easy, but if it's your day, it can be a fundamental push for the rest of the season."
