Nicolas Burdisso insists that Roma will have to be at their best defensively if they are to stop Milan this weekend.
The two teams meet at the Olimpico in a game which Roma need to win to keep their top four dreams alive, while the Rossoneri are looking for just a point which will mean Lo Scudetto.
"We'll have to be alert in defence against Milan, especially when you consider what we are playing for," he told Sky Sport Italia.
"We still have a chance to finish fourth seeing as we are just a point behind Lazio and we'll play for that objective until the very end."
Roma have the fourth worst defensive record in Serie A with 49 conceded, while Milan have the second best attack thanks to their 61 goals.
"We are an offensive side and sometimes we don't defend in great numbers," the Argentine added. "We sometimes struggle to find the right balance.
"In the important games this term we have always done well, it is in the other games where we have failed.
"The win in Milan earlier this season gave us the impression that we could fight for the title because this squad was built to do that. But we can still finish the season well."
