Internazionale moved 11 points clear at the top of Serie A as Romelu Lukaku and Lautaro Martinez struck in a 2-1 win over Sassuolo on Wednesday, the runaway leaders' 10th consecutive league victory.
Belgium striker Lukaku guided a header into the top corner in the first half before his Argentine partner finished off a counter-attack to continue the Nerazzurri's charge towards the title.
Sassuolo dominated possession at San Siro but were frustrated by a stubborn home defence until Hamed Traore curled home a superb finish five minutes from time.
"It was very important for us, to climb up the table and increase the gap," Martinez said after the match. "At the start of the second half of the season we had a talk, and now we're doing everything that the coach wants."
With nine matches left, Inter are firmly on course to win their first Serie A title since 2010 with 71 points, 11 ahead of second-placed AC Milan. Sassuolo remained ninth with 40 points.
