Nicolo Barella and Ivan Perisic scored in either half as Inter Milan moved top of Serie A on Friday with a 2-0 win at Fiorentina.
Antonio Conte’s side pulled one point clear of AC Milan to keep the pressure on their city rivals who host lowly Crotone on Sunday.
Inter bounced back after their midweek Italian Cup semi-final, first leg defeat to Juventus in the San Siro.
Italy midfielder Barella curled in the opener from a distance after half an hour with Achraf Hakimi setting up Perisic for the second seven minutes after the break to give Inter a first league win in Florence in seven years.
Conte sat out a touchline ban but Inter controlled the game against 12th-placed Fiorentina who were without injured French midfielder Franck Ribery.
“We’re not thinking about putting pressure on anyone, just our own journey,” said Conte’s assistant Cristian Stellini.
Fiorentina could thank goalkeeper Bartlomiej Dragowski for key saves, denying Barella early, with the Polish international also keeping out Hakimi, Perisic and Lautaro Martinez in the second half.
At the other end of the pitch Samir Handanovic saved from Giacomo Bonaventura and Cristiano Biraghi before the break.
Inter play Lazio next weekend before a derby clash with Milan on February 21.
