Lautaro Martinez scored twice and Romelu Lukaku was also on target as Inter overpowered rivals Milan 3-0 at San Siro.
Inter moved four points clear at the Serie A summit thanks to a resounding 3-0 derby triumph over faltering rivals Milan on Sunday.
Lautaro Martinez scored twice and Romelu Lukaku was also on target, helping Antonio Conte’s in-form side make it five wins in their past six league outings to take a firm grip on the title race in Italy.
This was the first time since April 2011 that the city rivals had met when occupying the top two positions in the table, with that season finishing with Milan crowned as champions.
A repeat for the Rossoneri looks increasingly unlikely as their worrying dip in form continued, though they were somewhat unfortunate to come up against a goalkeeper in supreme form.
