Watch as Joaquin Correa tore the Milan defence to shreds with two goals, before Ciro Immobile thumped home a third and rattled the woodwork.
It took just 77 seconds for Correa to find the back of the net, dribbling around Gianluigi Donnarumma to deposit into the empty net.
Correa thought he had a second, but it was disallowed for the tightest of offside margins with Simon Kjaer.

When Tucu did complete his brace, that too involved VAR, as referee Daniele Orsato stood by his decision that Lucas Leiva did not foul Hakan Calhanoglu.
Immobile was unlucky to see his lob come off the woodwork, while Donnarumma made a couple of great saves, but the striker completed the rout late on.
