Napoli will host Cagliari in their next game, while Inter Milan will have to win against high-flying Como to have any chance of retaining the title.
However, both Napoli manager Antonio Conte and Inter Milan boss Simone Inzaghi will not be in the dugout for their respective games. Conte was given a red card in Napoli's 0-0 draw against Parma, and Inzaghi was sent off in Inter Milan's 2-2 draw against Lazio.
The referee made the decision to eject Conte for arguing with players on the Parma bench, while Inzaghi was sent to the stands for his angry reaction to Lazio's late penalty.
