AC Milan coach Rino Gattuso says they must step up a level facing Chievo today.
Milan are third in the table after a run of four straight Serie A wins.
"It'll be very, very difficult," Gattuso said at his Press conference.
“It also will because Chievo are playing well and have nothing to lose. The game will require a great Milan performance, where we play well but also battle.
“We absolutely can't make mistakes as, unlike them, we have it all to lose. Therefore we need to play with clarity. The derby prepares for itself, but our next match is tomorrow.
“Rotation? Pressure causes tiredness. We've grown, but we're still insecure. Now, like I've said for some time, we need to raise the bar, also in terms of character.
“The time has come, otherwise we'll be sliced and diced."
