Gattuso: I could mark Messi in my dreams, or on the PlayStation with the Gattuso who weighed 20 kilos less

Gennaro Gattuso is painfully aware of the challenge he and his Napoli side face in trying to silence Lionel Messi when they take on Barcelona.

The Italians travel to the Camp Nou this coming week for the second leg of their last-16 tie, which Gattuso knows will be a tough ask.

"I could mark him in my dreams," Gattuso said when asked how to stop him, "or I could play my son's PlayStation and select Gattuso in his Milan shirt, when he weighed 15 or 20 kilos less."

Napoli captain Lorenzo Insigne went off in tears late on in their win over Lazio on Saturday, suggesting he picked up an injury that could rule him out against the Catalans.

"I haven't spoken to the doctor yet," Gattuso said.

"Lorenzo is the only one who has, so we have to assess him.

"I don't know exactly what's wrong and if I speak I'd only say things that might not be true."
