Inter Milan forward Lautaro Martinez was thrilled after matching Christian Vieri's goal record with a last-gasp strike to beat Napoli and win the Supercoppa Italiana.

The Argentine marksman fired home Benjamin Pavard's cross in the 91st minute to ensure the Nerazzurri lifted the trophy for a third consecutive year.

The result in Riyadh was further sweetened for Martinez, who matched the Inter goalscoring tally of club legend Vieri. 

He told Mediaset: "I didn't want to take off my jersey because of the yellow card but the emotion took over and I couldn't think. 

"It was a unique moment, I scored my 100th goal in the Coppa Italia final and today in the Supercoppa my 123rd goal allowed me to match a legend like Christian Vieri." 

Despite not being in top form, Martinez praised his team-mates for their determination. 

The 26-year-old added: "I am very proud and happy. 

"We were eliminated from the Coppa Italia, so this was an important objective. We played very well against Lazio and needed a great performance tonight. 

"It was tough. We had a day's less rest, we were not sharp but I am proud of this team for bringing home the third consecutive Supercoppa." 

The tournament was the first of its new format, with four teams taken from the winners and runners-up of Serie A and Coppa Italia. 

The competition holds little value for Napoli owner Aurelio De Laurentiis, who vented his frustration at the full-time whistle.

De Laurentiis, 74, said: "This Supercoppa that counts for very little ends up damaging the real focus of our season.

"The marvellous thing about this Supercoppa final four is that I didn't want it four or five months ago, because there are too many games already and we should not have added fixtures outside of Italy too. 

"I think from next season, with the increase of games that UEFA have already imposed in all competitions, there is no real reason for this trophy to exist."
