Striker Marco Borriello says second-placed AC Milan must step up a gear if they are to stop Inter Milan running away with the Serie A title again ahead of Saturday's visit to Fiorentina.
"Inter are superior. It almost seems that they are in a race on their own," Borriello told Friday's La Gazzetta dello Sport.
"We'll keep trying to close the gap until the end. But to be able to do so, we cannot have any more slips."
Brazilian defender Thiago Silva is expected to miss the match with a calf injury.
Frenchman Sebastien Frey should be back between the posts for Fiorentina after missing last week's 2-1 defeat at Chievo Verona with a leg muscle problem.
Inter midfielder Dejan Stankovic is likely to stand in for suspended Dutchman Wesley Sneijder in the playmaking position at lowly Lazio on Sunday. Sneijder was sent off in last weekend's 1-1 draw at Atalanta.
Pasquale Foggia is favourite to partner Lazio captain Tommaso Rocchi up front at the San Siro with Mauro Zarate suspended and Julio Cruz struggling for fitness.
Captain Alessandro Del Piero could be in third-placed Juventus's starting lineup for Sunday's home match against bottom side Catania at the expense of the disappointing Amauri.
Coach Ciro Ferrara's options are limited by Christian Poulsen's suspension and injuries to Gianluigi Buffon, Giorgio Chiellini, Mohamed Sissoko and Vincenzo Iaquinta.
Forward Giuseppe Mascara is suspended for the Sicilian visitors.
