Scott McTominay made his return from injury, but it was fellow Scotland midfielder Billy Gilmour who inspired reigning champions Napoli's comeback to beat Lecce 2-1 in Serie A.
The 24-year-old, who was making his second start after himself sitting out three months with a groin problem, played a superb defence-splitting pass to set up his side's equaliser shortly after the break on Saturday evening.
It found Matteo Politano free on the wing and his low cross was prodded home by Manchester United loanee Rasmus Hojlund.
With McTominay, missing for a month with tendon inflammation, on the bench along with fit-again former Manchester City midfielder Kevin De Bruyne, Napoli fell behind within three minutes as Jamil Siebert rose to head in from a corner for the 16th-placed visitors.
However, with McTominay and De Bruyne on at half-time, the comeback was complete when winger Politano volleyed the winner that revives Napoli's hopes of retaining the title.
With Internazionale held to a 1-1 draw at home to Atalanta, the Scots' third-placed side are nine points behind, with AC Milan one point better off than Napoli before playing Lazio on Sunday.
Meanwhile, Scotland midfielder Lennon Miller was a 67th-minute substitute as 11th-placed Udinese lost 1-0 at home to fourth-top Juventus.
In England, Scotland midfielder Kenny McLean scored Norwich City's second goal in a 2-0 win over Preston North End as the Canaries leapfrogged the visitors into 11th place in the Championship.
