After Darko Lazovic put Verona ahead early from a free kick, Ranieri made three changes during the break and two of the players he sent on - Antonio Candreva and Keita Balde - helped set up an equaliser from Jakub Jankto.

Candreva and Keita were at it again to draw a foul that led to a penalty kick converted by Manolo Gabbiadini, the other halftime sub.

Morten Thorsby then added another for 10th-place Sampdoria, which moved within two points of ninth-place Verona.

"Verona were more determined at the beginning and I had to make changes, because we were basically playing into Verona's hands and not doing what we had prepared during the week," Ranieri said.

A halftime substitute also made a major impact in Sassuolo's 3-1 comeback win over Fiorentina as Domenico Berardi converted two penalties after he came on.

Giacomo Bonaventura had put Fiorentina ahead before Berardi responded after the break and Maxime Lopez added another for Sassuolo, which is eighth.

Fiorentina, which is just two places above the drop zone, did not speak with media after the game.

Crotone striker Simeon Tochukwu, known as "Simy," converted a penalty for his 17th goal of the season but the last-place Calabrian club lost 2-1 at home to Udinese.

Rodrigo De Paul scored twice for Udinese but also received a direct red card for a foul in the 90th.

Also, Cagliari beat Parma 4-3 with an injury-time winner from Alberto Cerri in a matchup of the other two clubs in the relegation zone.-
