Juventus extended its lead atop Serie A to a commanding nine points Sunday in Rome, with a last-minute 1-0 win over visiting Catania, while second-place Napoli lost 2-0 at Chievo Verona.
Emanuele Giaccherini scored the winner for Juventus in the first minute of added time, finding the target from the edge of the box following a cross from Paul Pogba, the 19-year-old French forward discarded by Manchester United after last season.
"I hope my goal is the one that seals the title," Giaccherini said.
In Verona, Senegalese defender Boukary Drame put Chievo ahead 12 minutes in and French forward Cyril Thereau doubled the lead in the 43rd as Napoli goalkeeper Morgan De Sanctis had a disappointing day.
Napoli forward Edinson Cavani had a penalty saved by Chievo goalkeeper Christian Puggioni in the 13th.
With only 10 rounds remaining in the Italian league, Napoli at this point should be more worried about getting overtaken by third-place AC Milan, which is just two points behind after beating Genoa 2-0 Friday.
"There are still 30 points up for grabs," Napoli manager Walter Mazzarri said. "We have 10 'finals' from now until the end of the season."
Playing later were Inter Milan and Lazio, which are tied for fourth. Inter hosted Bologna and Lazio faced Fiorentina.
Elsewhere Sunday, Parma beat Torino 4-1 with a hat trick from Brazilian-born forward Amauri; Colombia forward Victor Ibarbo scored a hat trick as Cagliari defeated Sampdoria 3-1; Atalanta edged Pescara 2-1 with two goals from Argentine forward German Denis; and Siena beat Palermo 2-1 in a direct battle to avoid relegation.
