INTER Milan will retain their title if they defeat AC Milan in next weekend's derby after the league leaders beat Cagliari 2-1 yesterday.
Julio Cruz claimed the first goal and Marco Materazzi made it 2-0 before Cagliari hauled one back.
Second-placed AS Roma, six points behind Inter with three games left but with a worse head-to-head record, made sure the title race would continue for another weekend by thrashing struggling Torino 4-1 at home.
Fifth-placed Milan still have a lot to play for against Inter next Sunday after Filippo Inzaghi scored a hat-trick and Clarence Seedorf added the gloss in a 4-1 win at Livorno.
Daniele Gastaldello's header deep into stoppage time gave Sampdoria a 2-2 draw at fourth-placed Fiorentina and means Milan are just two points behind the Florence club in the race for the final Champions League qualifying spot.
Juventus, in third, secured their berth in the Champions League qualifiers with a 5-2 win over Lazio. David Trezeguet and Alessandro Del Piero both netted in their personal battle to be Serie A top scorer with 19 and 18 goals respectively.
