Manager John Sheridan was disappointed to lose yesterday’s game but could not fault his player’s effort and endeavour.
Charlton raced into a two goal lead but a penalty from Craig Davies and a debut goal from Eoin Doyle levelled the scores.
Latics were reduced to 10 men following the dismissal of Ousmane Fane and two goals from the visitors looked to put the game beyond doubt.
However, Latics did pull a goal back through Jack Byrne on his league debut but that was not enough to get anything from the game.
Sheridan said: “I’m disappointed to lose the game and again we have started the game poorly. We are doing it too many times and giving ourselves a harder battle.
“It’s a wonder strike for the first goal but I just thought we were very flat. We were slow in everything we were doing and they get the two goals.
“I don’t want to be taking anyone off early but I do think the substitution changed the game.
“We were on the front foot and I thought in the last 20 minutes of the first half we were excellent and possibly should have gone in level at half time.
“We came out well in the second half and got the equaliser and I could only see one winner and then it’s comical.
“First of all we should have had a penalty in the first five minutes on Eoin Doyle.
“I don’t think there was a bad tackle in the game. I felt Ousmane Fane won the ball cleanly and it’s a downer for us because we were right on top of the game and had the momentum.
“It’s disappointing to end up losing but credit to the players because they showed good character and the fans got right behind the team.
“We’re five without a win now and that’s not good enough for me but if you show that endeavour then the fans are going to be with you and believe that we can win games.
“I would have liked to have played rubbish and got the three points because that’s the position we are in at the moment.”
Doyle and Kean Bryan made their debuts for Latics and the manager praised their impacts.
“I thought they all did okay,” commented Sheridan. “You can see from Eoin’s goal that he is a clever player and he’s intelligent for Jack Byrne’s goal as well.
“Craig Davies hasn’t played much but he came in and did well today. Young Kean Bryan I thought did okay and he got in good positions.
“You can see he is short of match time but they all did alright.”
