Goalkeeper Gianluigi Donnarumma dedicated AC Milan's Supercoppa Italiana success to club president Silvio Berlusconi after they beat Juventus on penalties.
The 17-year-old made a vital contribution to the success in Doha, saving from Paulo Dybala in the shootout before Mario Pasalic converted the deciding spot-kick.
Donnarumma, who picked up the first silverware of his professional career, felt the triumph was even more satisfying given that Milan had eight Italians in their starting lineup.
"I am so happy, I can't even describe it,'' he told the club's official website. "We prepared for it well and we were on the same level as Juve.
"To win with all these Italian players in the team really makes me proud.
"The manager gave us that something more, we trust him a lot.
"This victory is for our president.''
The Rossoneri fell behind to Giorgio Chiellini's volley at the Jassim Bin Hamad Stadium, but Giacomo Bonaventura levelled matters before half-time as the tie finished 1-1 after extra-time.
Vincenzo Montella's men made a bad start to the shootout when Gianluca Lapadula saw his kick saved by Gianluigi Buffon, but Mario Mandzukic's miss and Dybala's unsuccessful effort left Pasalic to seal a 4-3 win as Milan equalled the Turin club's record of seven Super Cup successes.
Juve captain Buffon felt his side paid for not building on their early breakthroughs in the game and the shootout.
"It's a shame, especially as we led both in normal time and on penalties,'' he told juventus.com. "We could have avoided the match being dragged out.
"We should have realised that we could have killed off the game in those blistering opening 25 minutes because it was an even contest after that. AC Milan showed determination -- they played well.''
The veteran keeper also reflected on a positive 2016 for the Bianconeri during which they won a fifth successive Serie A title and the Coppa Italia.
"[It's been] a good year,'' he added. "There were lots of good things -- it hasn't ended as we would have liked but that's part and parcel of the game.''
