David de Gea was the hero for Fiorentina, saving two penalties as they claimed their second victory of the Serie A season in a chaotic encounter with AC Milan.

The Spaniard got down low to his left to save Theo Hernandez’s first-half spot-kick before superbly diving to his right to prevent Tammy Abraham scoring his penalty in the second period.

Former Manchester United goalkeeper De Gea, 33, signed for the Italian club in August and his performance was key to the 2-1 win against Milan.

Yacine Adli and Albert Gudmundsson scored for the hosts, with Christian Pulisic levelling in between. It was a contest that also saw Milan keeper Mike Maignan save Moise Kean’s penalty, Fiorentina boss Raffaele Palladino sent off in the closing stages, and a red card issued to Milan defender Hernandez after the final whistle.

Scott McTominay scored after 25 seconds as Napoli beat Como 3-1 to continue their fine early season form and stay top of the Italian top flight.

Romelu Lukaku also scored for Antonio Conte’s team, and they sit two points clear of second-placed Inter Milan, who beat Torino 3-2 thanks to a hat-trick from their France forward Marcus Thuram.

Juventus conceded their first goal of the campaign as they were held to a surprise 1-1 home draw by Cagliari on Sunday.

Razvan Marin lashed home an 88th-minute leveller from the penalty spot after Dusan Vlahovic’s first-half spot-kick had put Juventus ahead.

Thiago Motta’s Juventus side, who were without Nicolas Gonzalez, Arkadiusz Milik, Timothy Weah and Gleison Bremer, were made to pay for a loss of intensity.

“We took our foot off the pedal after our goal, and we can’t do that. We need to keep attacking, and attack well. What happened is all our own fault,” said Motta.
