Wolves ran out 3-2 winners on the night with Nouha Dicko netting a brace before the hosts fought back to level 2-2.
Bright Enobakhare sealed Wolves' victory in the 88th-minute, showing real persistence to put goalkeeper and defender under enough pressure to force a mistake and present him with a tap-in.
With all teams in Wolves' Checkatrade Trophy group now tied on three points, Sellars hopes Tuesday's result will give his side a lift going into the Accrington Stanley fixture at Molineux.
He said: “We’re all on three points now and we have one more game to play at home to Accrington.
“It’s a great opportunity to go and progress in the competition.
“As I said before I wanted to try and get more games at this level for the boys because I think it develops them a lot more than our present programme.
“Over the two games I would like to think that people saw that Wolves have some good young players and that we’re doing things in the right way.
“From our point of view, all I can really look at is the hope that we’re learning, getting better and that our lads will progress to have good careers.
“It’s been a great introduction for us as an Under 23s team and hopefully we can take something from it and get into the next stage of the competition."
Looking back at Tuesday's game, Sellars said: “It was a game that, at 2-0 at half time, I expected to be a bit more comfortable.
“I expected them to come out and then a mistake let them back into the game and gave them a bit more confidence.
“They really pushed on and got the equaliser although I felt we could have got a couple of goals in that time, with Bright hitting the post and their ‘keeper making a great save from Jed.
“It came back to 2-2 and at that point you’re worried for two young centre backs but I thought they coped really well.
“Then Bright, with a real bit of perseverance, gets the winning goal.
“You can talk about pressure as a player but there’s nothing like playing in it and putting yourself under it.
“I was really pleased that they got a win to take some real confidence from it."
Nouha Dicko continued to work towards full match fitness with another outing for Scott Selllars' side and the Under 23s Coach was full of praise for the striker.
“Each game he’s had with us is building his fitness, building his confidence," explained the coach.
“I thought in the last game against Middlesbrough he looked really sharp and I thought, again tonight, he went up another notch.
“Every time he got the ball he looked electric and we looked liked we were going to cause havoc.
“He looks bang at it and after tonight I think he’s ready to go.
“We were a stepping stone for him to get back to his fitness, I hope he’s enjoyed it.
“He’s been great with the other lads, he’s looked after them and scored some good goals."
