Inter Milan beat Napoli to win the Italian Super Cup after both teams paid tribute to Italy’s all-time top scorer Gigi Riva.

Lautaro Martinez scored the winner in injury time as Inter wrapped up a third straight Super Cup success.

But the match, held in Riyadh, Saudi Arabia, between current Serie A champions Napoli and Coppa Italia holders Inter, was overshadowed by Riva’s death, aged 79.

A minute’s applause was held before the second half after the news filtered through during the first half.

Riva scored 35 goals in 42 appearances for Italy and was a member of the squad which won the 1968 European Championship and lost in the 1970 World Cup final to Brazil.

He was also a prolific goalscorer for Cagliari, leading the Sardinian club to their only Serie A title in 1970.

It appeared that no one was going to find a goal to settle the match, until Martinez finally broke the deadlock two minutes into added time.

Inter dominated the first half and created the first chance when a long Matteo Darmian throw-in found its way through to Federico Dimarco, whose volley was deflected inches wide.

Martinez then headed wide from Francesco Acerbi’s cross and Henrikh Mkhitaryan fired over 20 yards out.

Martinez had the ball in the net after 40 minutes when he tapped in Marcus Thuram’s cross but an offside flag curtailed any celebrations.

Napoli’s first real opening came six minutes into the second half when Stanislav Lobotka fed Khvicha Kvaratskhelia.

The Georgian cut back inside and tried to curl the ball towards the far post but his effort was beaten away by Inter keeper Yann Sommer.

Napoli were reduced to 10 men on the hour after Giovanni Simeone was shown a second yellow card for a foul on Acerbi.

Inter set about trying to press home their numerical advantage but Thuram twice missed his kick in front of goal and Martinez volleyed over the crossbar.

Frustrated Napoli coach Walter Mazzarri was shown a yellow card before Mkhitaryan tried his luck again, only to send his shot too high.

The match looked destined for penalties until Alexis Sanchez fed Benjamin Pavard down the right.

Pavard pinged in a low cross which was swept home by Martinez to wrap up a super treble for Inter.
