Lorenzo Pellegrini grabbed a late winner for Roma as they beat Spezia 4-3 on Saturday.
Borja Mayoral's opener was cancelled out by Roberto Piccoli, but three goals in six second-half minutes from Mayoral, Roma wing-back Rick Karsdorp and Spezia forward Diego Farias set up a frantic finale.
Substitute Daniele Verde thought he had earned a stunning draw in the 90th minute when he pounced on a Chris Smalling error to score. But Pellegrini swept in a winner with seconds left on the clock to avenge Tuesday's 4-2 Coppa Italia defeat.
