Milan: Romelu Lukaku scored after just 21 seconds as he bagged a brace in a 4-1 thumping of Cagliari that fired Inter Milan into the last eight of the Italian Cup.

Belgian Lukaku has looked a player reborn since moving to Italy and his double took his hot streak to six goals in his last four appearances.

The 26-year-old lashed home his opener with the match barely under way and then, after Borja Valero had made it 2-0 in the 22 minute, headed home his side’s third.

Lazio and Napoli both cruised through with comfortable wins over second-tier sides Cremonese and Perugia to set up a mouth-watering last eight tie.
