Inter Milan are now four points clear at the top of Serie A after putting neighbours and title rivals AC Milan to the sword in a complete performance at the San Siro.
Romelu Lukaku and strike partner Lautaro Martinez combined for the latter to break the deadlock after just five minutes of the table-topping clash, with the Argentine finishing off a superb team attack early in the second half to double the advantage.
Lukaku got the goal he deserved for his overall efforts, capping a surging run forward with a strong finish shortly after the hour mark to put the result beyond doubt.
Ivan Perisic, Christian Eriksen and Achraf Hakimi were superb for the 'visitors' as well, while veteran goalkeeper Samir Handanovic produced three superb saves just after the interval — two of which to deny Zlatan Ibrahimovic at point-blank range — to keep his side ahead while the game was still close.
