With no doubts, Lukaku is a diamond that needed polishing. The Belgian striker scored twice including a goal after 21 seconds of play. He eased his side into quarter-finals of the Coppa Italia.
Lukaku took advantage of a panicked back pass form Christian Oliva to ram home Inter’s first goal in the opening minute.
The Belgian striker then added a second ruled out by VAR and missed a chance to touch home Nicolo Barella’s powerfully struck cross. But the veteran Borja Valero behind him scrambled it over the line for a 2-0 lead after 21 minutes.
Barella was the provider again after a quickly taken corner kick for Lukaku’s second four minutes into the second half. Andrea Ranocchia finished off the scoring with a replica header in the 80th minute.
Cagliari scored a smartly fashioned consolation in the 71st minute. Alberto Cerri back-heeled the ball into Oliva’s path who finished with a powerful strike.
Meanwhile, Napoli and Lazio set up a meeting in the last eight. Both won at home against second-tier opposition with Ciro Immobile continuing his scoring ways for Lazio to a 2-0 win over Perugia.
The Napoli captain, Insigne broke the deadlock in a last 16 tie featuring three first-half penalties with a 26th-minute spot-kick. This after Hirving Lozano had been fouled. He then converted another 12 minutes later after a handball by Pietro Lemmello.
