Karl Robinson felt his side did enough to book an FA Cup fourth round spot, despite the disappointing 3-1 defeat to Wigan.
Luke Chadwick fired Dons ahead after 10 minutes, but Nick Powell equalised with 10 minutes to go to send the tie to extra time. He struck again just after the restart, and Marc-Antoine Fortune finished it off a minute before the break.
But over the two games in normal time, Robinson felt his Dons side were worthy of a place in the fourth round.
“We didn’t think we deserved to lose the game,” he said. “Over 180 minutes, I felt we were dominant and the better team.
“At 1-0, we just didn’t have the rub of the green. We hit the post and their keeper made some wonderful saves.
“I thought Samir Carruthers was absolutely outstanding. The whole team were good. We were very compact against two of the quickest strikers in the Championship.
“There’s massive learning curve to come from this game though, and we can look back fondly on our FA Cup run again. I’ll take the positives from it. I’m proud of the players, we’ve done really well.
“We have been beaten and we accept that though. Tactically, we got it right but it just wasn’t to be.
“I can’t ask for more from the players.”
Wigan were fortunate to go into extra time with a full compliment of players after Ben Watson checked Daniel Powell’s run as he looked to go through on goal, but was only shown a yellow card.
Robinson did ask referee James Adcock whether it was a sending off, but was told otherwise.
He said: “At first I thought he should have been sent off but the referee told me the ball was long gone. I thought the referee was excellent though, so I can’t knock him.
“They were fouling us in a very continental way, and we don’t seem to do that. That’s what you’ve got to do to win matches. We don’t seem to do that.”
Without Chris Long, and with Izale McLeod on the bench, Robinson opted to use Daniel Powell as the striker.
Unfamiliar with the position, Robinson felt Powell did well.
He said: “I thought he did well and created a big threat. He’s not a natural finisher and that’s something he has to work on, but he’s shown he can go up there if Chris Long can’t do it over a long period of time.
“We stuck Alan Smith up front and went 4-4-2, and he did well and even Antony Kay went up there he should have scored!
“We had a centre back up there, and if he’d squared it to George Baldock he had a tap in. But it wasn’t to be.”
But for now, with nothing but League 1 to concentrate on now for Robinson’s side for the remainder of the season, the manager hopes the defeat will be a blessing in disguise come April.
“I’ll tell you at the end of the season,” he said. “This defeat gives us a chance to rest and get our sea legs back.
“But we’ve got two massive games ahead of us now, that we have to go at full throttle.”
