"There is a lot of anger within us that will be useful on Sunday, as we can pour that out against Catania, proving we can play our style of football and bring home results," said the midfielder.
"Well, more than anger it is an eagerness to get going. Milan are a very elegant club and can accept defeat without ever glossing over its errors. We know that we can make up for this and do better in the future."
Seedorf also said: "I would not change anything about this side as, apart from the result, we did everything very well in Palermo. There were only two incidents we could have done better on, but one usually doesn't pay for such small errors as much as we are now. I can see Milan improving and I cling to that."
