Inter strengthened their position at the Serie A summit as Lautaro Martinez's late header secured a slender 2-1 win over Torino on Sunday.
The Nerazzurri never looked like scoring during a dismal first half, but they forged ahead in the 62nd minute when Romelu Lukaku slotted home from the penalty spot.
Antonio Sanabria pulled the hosts level eight minutes later, yet Inter celebrated an eighth consecutive top-flight win courtesy of Martinez's 14th league goal of the season five minutes from full-time.
The result moved Antonio Conte's side nine points clear at the top of Serie A, although Milan had the chance to restore a six-point gap by overcoming Napoli later on Sunday.
Martinez headed wide early on for Inter, but it was Torino who came closest to scoring during a largely tepid first half, in which the visitors failed to register a single shot on target.
Simone Verdi's free-kick from the left channel found Lyanco at the back post and the defender's header crashed back off Samir Handanovic's left-hand post.
Conte replaced Roberto Gagliardini and Ivan Perisic with Ashley Young and Christian Eriksen shortly before the hour mark in an attempt to inject some life into his side and it paid off almost instantly.
Armando Izzo brought down Martinez in the area and Lukaku stepped up to stroke home his 19th Serie A goal of the season.
Salvatore Sirigu denied Achraf Hakimi soon after, before Torino pulled level 20 minutes from time, Sanabria firing in from close range after Handanovic had kept out Simone Zaza's initial effort.
Martinez had the final say, though, superbly heading home substitute Alexis Sanchez's cross in the 85th minute to seal all three points and crank up the pressure on Inter's title rivals.
What does it mean? Inter march on
Conte's men were far from their best against Torino, but superior quality eventually told against a side who have still won just three league games all season.
Their two goals came from just three shots on target - the same number as Torino - but Conte will point to 68.6 per cent possession and 371 more passes (687-316) as proof his side deserved to see off Davide Nicola's outfit.
Martinez shines for Inter
Martinez was at the heart of Inter's triumph, winning the penalty for the first goal and steering a fine header past Sirigu for the winner. He is up to 14 goals in 27 Serie A matches this season, matching his best-ever return in the Italian top flight.
Perisic off the boil
The Croatia international has impressed this season, but this was a rare off day. Perisic struggled in his 56 minutes on the pitch, playing just one key pass to his team-mates and failing to take a single shot.
Both sides face Sassuolo in the next week, with Torino hosting them on Wednesday before Inter take on Roberto De Zerbi's side at San Siro on Saturday.
