Karl Robinson was able to experiment with new partnerships with half an eye on Sunday's game against Port Vale in the 1-0 win against Peterborough on Tuesday night.
Kieran Agard's strike five minutes before half time was enough to see Dons past Grant McCann's side at the ABAX Stadium in the much-maligned Checkatrade Trophy, in a game Robinson felt he could take a lot of positives from.
From Jack Hendry's solid debut, Ed Upson's dominant midfield performance alongside Samir Carruthers, an enthusiastic Brandon Thomas-Asante and another goal from Agard, the manager felt his side fully deserved the win, and should have won by a lot more.
"We should have had more," said the manager afterwards. "We played very well. We're in good form, and there's an air of confidence.
"A lot of what we did today was in preparation for Sunday, building new partnerships.
"I felt Jack Hendry did wonderfully well, we've got another clean sheet and two very convincing wins. We're starting to score goals too, but we should have had more too. We've played really well and we're really happy.
"It's my first victory here as well, and it has eaten away at me. I wanted the win here on my CV. I've been here and been beaten a lot so I wanted that one!
"Peterborough finished off with a very strong side, and we've had to play well and we've shown that.
"It's important to get a balance in the team in games like this."
The name on all the fans' lips though was once again 17-year-old Brandon Thomas-Asante, who played a big part in almost everything Dons did going forwards.
Robinson added: "He needs to learn the other side of the game, his game management needs to be better. His natural enthusiasm can be exciting but also a hindrance, so he needs that balance.
"It's a vital learning curve for him but he certainly excited me tonight. Ben Tilney was excellent too, but you'll be hard pushed to find a bad player on the pitch."
