AC Milan coach Leonardo admits he's been disappointed with recent results.

The Brazilian admits Milan have frozen in key games this season.

"We expected a little more in terms of results, but the team is playing well and now I expect confirmation of that," said Leo. "There have been many crucial games this season and we didn't always make the most of them.

"I care a great deal about tomorrow's match with Sampdoria. We need an important performance that sends a signal to us and to others. You can't take anything for granted this season.

"Sampdoria are in fourth place and highly motivated. Antonio Cassano is a very instinctive player and I like him a lot, while he makes a great partnership with Giampaolo Pazzini. Samp can target an important achievement."
