Daniel James converted the winning penalty in a shoot-out to give Manchester United victory over AC Milan on Saturday and six wins in as many pre-season matches.
The 21-year-old Wales international, who signed from second tier Swansea in the close season, sealed victory after David de Gea had saved a spot-kick from Daniel Maldini, son of Milan and Italy legend Paolo.
United's 5-4 victory — its other five victories included beating Tottenham Hotspur and Inter Milan — in the shoot-out came after the match ended 2-2 but was not enough for it to win the International Champions Cup with the honours going to Portuguese side Benfica instead.
“It's amazing. Today was a difficult test but it showed the spirit to come from behind,” James told MUTV. “To score that last penalty, especially here in Cardiff, is very special.”
The English side's triumph came despite the absence of Belgium striker Romelu Lukaku, who is expected to leave the club on a potential swap deal with Argentinian Paulo Dybala from Juventus, and France's World Cup-winning midfielder Paul Pogba.
Pogba purportedly missed the trip to Wales with a back injury although the Daily Mirror claimed he had sought to seal a move away to Real Madrid by not travelling with the squad.
United took the lead when Marcus Rashford opened the scoring with a delightful individual effort, dancing through two rather feeble efforts at tackles before his shot took a deflection off Milan skipper Alessio Romagnoli.
The visitors levelled in the 25th minute, Suso curling one into the net from outside the penalty area. de Gea denied Suso a second seven minutes before the break.
Suso was at the heart of the goal that gave Milan the lead on the hour mark, his cross being flicked on by Samu Castillejo which hit United central defender Victor Lindelof's head and went in.
United struck back as substitute Jesse Lingard's shot beat former Liverpool goalkeeper Pepe Reina with 18 minutes remaining.
