Inter Milan completed a domestic double after easing to a 2-0 victory over Lazio in the Coppa Italia final at the Stadio Olimpico.

The Nerazzurri continued their brilliant domestic campaign in Rome by picking up their second trophy in 10 days after lifting the Serie A title with three games to spare.

It was a sense of deja vu for Maurizio Sarri's outfit, who lost 3-0 at home to the newly crowned champions in league action last weekend.

Adam Marusic's own goal and Lautaro Martínez's tap-in put Inter in control at the break and while they could not add to the scoreline, they had their opponents at arm's length for the whole of the second half.

Inter Milan dominated possession from the outset with Lazio, playing on home soil for the cup final, struggling to get out of their own half.

Cristian Chivu's side were camped on the edge of the Biancocelesti's penalty area, with only a Martinez header of note until they broke the deadlock in the 14th minute.

Federico Dimarco's inswinging corner was glanced on by Marcus Thuram, which was enough for Marusic to miscue his header into his own goal from six yards.

Nicolò Barella tried his luck with a tempting half-volley but ballooned high over the crossbar, while Denzel Dumfries saw a goalbound effort deflect behind as Inter pushed for a quickfire second goal.

They should have done better from the resulting corner as Thuram steered wide before doubling their advantage 10 minutes before interval.

Dumfries nicked the ball off Nuno Tavares outside the Lazio box before sliding a pass for Martínez to tap into an empty net from close range.

Piotr Zielinski forced Edoardo Motta into a smart save from long range before their opponents had their first real chance when Gustav Isaksen's effort was deflected narrowly wide on the stroke of halftime.

Lazio were on the front foot at the start of the second period as they tried to get back into the game, with Tijjani Noslin firing just wide.

Kenneth Taylor was next to miss the target for the Sarri's side as they finally had a foothold in the game, but their quality in the final third was lacking.

Luis Henrique could not find the target from the corner of the six-yard box just two minutes after coming on for Inter, while Matteo Cancellieri volleyed over at the other end of the pitch.

Boulaye Dia had a brilliant chance to halve the deficit, but Josep Martínez produced a fine save from close range to deny the Lazio substitute.

Zielinski had one last effort to add gloss to the scoreline, while Dia's late header into the hands of Josep Martínez summed up Biancocelesti's night in front of goal.
