Striker Son Heung-Min was among the Tottenham Hotspur players left without a winner's medal during the awards ceremony for the Europa League final on Wednesday.
UEFA president Aleksander Čeferin appeared to be caught by surprise when the medals ran out before all Tottenham players had received them following the team's 1-0 win over Manchester United.
UEFA later said that the problem occurred because Tottenham sent too many people to receive their medals during the ceremony.
The European governing body added the clubs had been informed that only 30 medals would be presented on stage to each club. It said 20 further medals were given to the club following the ceremony for distribution to players and staff.
Son, who lifted the trophy in front of his teammates in the awards ceremony, was among the few players who didn't receive his medal on the field.
It was Tottenham's first major title since 2008.
The club have confirmed their plans to continue their celebrations with an open-top bus parade on Friday, with the route ending at the Tottenham Hotspur stadium.
Cristian Romero also joked about the medals gaffe.
"I don't know, they ran out of medals and couldn't give me one," Romero told ESPN in a light-hearted moment on the pitch after the win.
"But the most important thing is that we are Europa League champions and my name will be forever included with this club, that is the most important.
"It was a tough season for us," he said. "We deserved to finish like this because no one knows what goes on behind closed doors at the club. Despite everything, we always put our best foot forward. We had too many injuries, and there was always criticism about this team and the coach, and today we silenced them all."
