Napoli, the defending champions, drew 0–0 away at hosts Como on Saturday, leaving Inter Milan just one point away from clinching the Serie A title.
Inter sit top of the standings, nine points ahead of Napoli, who have three matches left; Inter will secure the league title if they can at least draw at home against Parma on Sunday.
Como, meanwhile, boosted their chances of qualifying for European competition for the very first time.
Fabregas’ side sit fifth in the table on 62 points, two points ahead of Juventus, who host the relegated Hellas Verona on Sunday. Como are eight points clear of seventh‑placed Atalanta, while the first six teams in Italy’s top flight take part in continental competitions.
