Napoli came from behind to beat Bologna and return to the top of Serie A.
Bologna striker Joshua Zirkzee opened the scoring in the 41st minute when he received a pass from Andrea Cambiaso inside the box and fired into the bottom right-hand corner of the net.
Juan Jesus equalised just before half-time, with Hirving Lozano putting the hosts ahead in the 49th minute.
Musa Barrow's long-range shot made it 2-2, but Victor Osimhen got Napoli's winner, lifting a finish in the net.
Napoli, aiming to become Italian champions for the first time since 1990, have 10 wins in a row in all competitions and are on 26 points, two ahead of Atalanta, who beat Sassuolo 2-1 on Saturday.
