Tony Philliskirk’s youth team were beaten 4-2 away to Doncaster Rovers on Saturday.
Latics took an early lead through Brendy Glackin, however, a minute later Doncaster equalised from the penalty spot.
Jamie Stott restored the youngsters lead from the spot but five minutes after the break, Rovers equalised for the second time.
With 15 minutes of the game remaining, two quick goals from the home side secured Doncaster Rovers the victory.
Speaking about the game, Philliskirk said: “I’m disappointed with the result but I can’t say I’m disappointed by the performance.
“I thought we created a lot of chances throughout the game and we dominated at times but we just missed that lethal touch in front of goal.
“We come away disappointed because we could and maybe should have scored more goals but the goals we did give away were sloppy and people have taken blame for them.
“I was impressed with Doncaster, though. They moved the ball well and were physical in a good way and that’s something we lack I think.
“I’m not saying we should have beaten Doncaster, but I’m saying we shouldn’t have got beat. The chances we had, we should have scored more goals and we conceded sloppy goals.
“It’s happened too often this season where we have dominated games, missed chances and they have gone up the other end and beat us.
“Games are won and lost in both boxes and I think we don’t dominate both boxes and that is a worry.”
Injuries have plagued Philliskirk’s squad and he added: “Rahul Parmer has been really ill and not trained since April but he walked in today and that’s great news, however he’s not trained since April so he needs a special programme to get him back into full fitness.
“Scullion is out for the season, Mantack had a knee operation so he’s a long term injury. Jake Hargreaves had a ruptured thigh and he’s long term as well.
"Ronaldo Brown is making slow progress but at least it is progress so we may see him in a couple of weeks but I can’t do anything more than move under 16s up to play.
“We are so short of numbers at the moment but I’ve got to tailor the training programme Monday to Friday and make them pretty fresh for the next few games.”
Philliskirk’s men have a free weekend next week, allowing players time to recover from injuries but their next game is at SportsDirect.com Park in the FA Youth Cup first round against Chester City.
