Ainsworth – drenched in champagne after joyous celebrations with his players – told Sky Sports: "That was just amazing, you know.

"We can't afford the best footballing players, but heart and determination and that was a Wycombe performance.

"I'm so, so proud of the boys. They just ground it out, I can't believe it. I still can't believe that we are a Championship club."

The Chairboys, tipped for relegation at the start of the season, defied the odds to qualify for the play-offs, having been raised from eighth position in the table when the season came to a premature close to third on points-per-game.

Ainsworth suffered penalty shoot-out heartbreak with Wanderers on his previous visit to Wembley, in the League Two play-off final in 2015, but was able to create history this time following a cagey game.

He said: "Rochdale and Accrington were down there with us, but we were right down there budget-wise. I had nine players on the first day of pre-season and two of them were trialists."

Former Wimbledon player Ainsworth added: "There was only ever one Crazy Gang. We'll come up with a name for ourselves. At the moment I don't know what that is.

"All I can tell you is we are a Championship club and I'm over the moon."

The U's pushed forward in search of a second equaliser in the last 10 minutes, but Wycombe held firm to clinch promotion to the Championship.

Jacobson, whose second-half penalty sent Wycombe to the second tier for the first time said it was "ridiculous" what his side had achieved.

"It's ridiculous. I can't believe what we've just done," Jacobson told Sky Sports. "To go back 11 months, first day of pre-season, nine players, favourites for relegation.

"Where we've got to now is ridiculous. It's stupid what we've done today. But that's us, that's Wycombe to a 'T'.

"We can score goals and do well in set-pieces, we can defend well as a team.

"We've got strikers and wingers who are unbelievable going forward, but happy to run back 50 yards to get a tackle in. That sums us up."
