The City goalkeeper proved the final hero, with a stoppage time penalty save preserving the win for the Young Lions.
Cole Palmer‘s deflected free-kick proved the only goal of the game, with Taylor Harwood-Bellis and Tommy Doyle also helping England claim the title for the first time since 1984.
Speaking to Channel 4 after the match, Trafford insisted that he and his team-mates had targeted being named U21 European Champions ahead of the tournament.

“I’m very happy. I’m very happy for the team, very happy for all of my family, friends and the coaching staff,” he said.
“It was a massive group effort and we delivered.
“This was what we set out for at the start of the tournament and we achieved it. We’re all really proud of ourselves.”
England’s 1-0 victory ensured that Trafford became the first goalkeeper in Euro U21 history to keep six successive clean sheets.
Indeed, the Young Lions didn’t concede a single goal throughout the tournament.
Unsurprisingly, that record was a particular source of personal pride for the City stopper.
He said: “It means a lot for us, the record, because it will take a massive effort to be broken.
“We’re a very good team and we believe nobody could score against us. We showed it.”
