The Head Coach gave his assessment on the performance at Moor Lane in an encounter that saw his side grab a point in the closing stages.
Despite coming away with a point, Maamria was slightly frustrated his side couldn't use the momentum at the end to get the important win, but was honest that an improvement needed to happen from the first-half reaction.
"It was there for the taking. We finished the game strongly, but we're not that team yet to sense those moments because if we were at that level we would've won that game.
"Having said that I thought we were really poor in the first-half, we started the game really poorly and was against everything we prepared for.
"Then to give the referee a decision to make and give them the penalty, we knew it was going to be big game and was going to be a sellout so it wasn't a very good start.
"That give them momentum because when you come here you need to manage the environment, play in their half and try and capitalise on it.
"We had a moment before they scored the penalty where Maouche is on the edge of the box in a 1v1 and was disappointed with that one as he should've took him on and got the shot away.
"That's the moments where we need to be better because when we get to that level, we score before they score and with that finish at the end as well we'd win it."
A huge positive from the match was striker Danny Rowe scoring his first goal in the EFL and in the process opening his account in an Oldham shirt.
"Well I'm glad we signed him because I don't think without Rowe we'd score that goal.
"Our recruitment has got to be spot on, with Rowe that's what he can bring and he has been very good in the last two games to be fair and when that moment came to him you wouldn't want that ball into anybody else.
"Although it didn't come off on his right, the second opportunity on his left foot what a finish that was.
"I'm delighted for him he's scored his first goal and hopefully there's many more to come as well."
Looking for an improvement at the break, the Oldham man in the dugout was impressed his changes made the desired impact.
"The subs were fantastic when they came on. We had a difficult week and Missilou was one of those suffering with sickness that's why he was on the bench, he came on with Dearnley and Gevaro and those three were lively and gave us the momentum to finish that last half-hour of the game as strong as possible.
"I thought that was a big positive in what was always going to be a difficult game and it was a much, much better performance in the second-half."
Whilst a bit of luck went against Latics again as another penalty was conceded away from home in quick succession in 2020.
"I've looked at the incident and I don't think the penalty was a penalty. It was one of those things you see in the box every week, Zak and Adam Rooney were both pulling each other.
"But Rooney was never going to get to the ball and it was a big call to make for the referee and it wasn't a clear-cut penalty.
"Having said that we shouldn't put ourselves in that position anyway.
He continued: "It's been difficult this season and we know changes are being made. I'm ambitious, I see the potential, I back myself to get it right and I will get it right and I know what winning looks like.
"100% we're not there yet and I know the changes we need to make to be that team to win games.
"It's a work in progress and I came here to sort it out. I'm in the middle of that and I've said it all along that I need two transfer windows to get the players like Rowe to come in and make that difference to us.
"We've just got to make sure that player, fans, staff stay together, believe in the long process. I've no doubt in my mind we'll finish the season strongly.
"When we get the right team on the pitch, hopefully McCann is going to come back soon and with Piergianni in the back four we will be a force to be reckoned with and it will give us a lot of optimism."
