Accrington Stanley manager John Coleman admitted that his side have got to be more clinical when going forward, much like Peterborough United were as they scored four second half goals to inflict a 4-0 away defeat on the Reds.
After the first half ended goalless, Darren Ferguson's side scored four times after the break and Coleman praised the hosts for how clinical they were in front of goal.
"4-0 flatters Peterborough tonight but there you go they were clinical in front of goal, I think they had five attempts in front of goal and scored four of them so you can't beat that.
"They're a good side Peterborough, we're not under any dillusions about that but they weren't four goals better than us tonight."
Striker Offrande Zanzala had a goal controversially disallowed in the first of 12 added minutes at the end of the first half and Coleman explains how the first goal was always going to be crucial.
"I thought we were comfortably the better team during the first half and we've scored a perfectly good goal, for some reason now your shoulder has become your hand and it's unforgiveable to make a mistake of that magnitude.
"The first goal was always going to be crucial during games like this and this proved to be the case.
"They've said it was handball but it hits him on the shoulder, if the ball could have hit him on the arm then it couldn't generate that power, no one can generate that power with a muscle, so it can only hit a bone, the only bone it can hit is his shoulder and that's why it's gone in, it's a perfectly good goal."
The hosts' first goal of the game in fact came from a Stanley set-piece and Coleman knows that his team have to do better to ensure they don't end up in situations where they can be countered against.
"We always believe we'll try and score but we've left two against two at the back and they should be able to cope comfortably and we've tried to play offside, but he wasn't offside and we've only got ourselves to blame.
"Sam Finley's done ever so well to go past the first lad on the edge of the box but he's got to shoot or play somebody in, he's put a weak cross in that was easily cleared and we've paid the price for it.
"I think if Peterborough don't score the first goal then they don't score at all and that's the harsh reality of it, but they're too good of a team to gift them a second goal after that.
"They are a very good attacking team, you've seen how many goals they've scored this season, but even in their wildest dreams at half-time they wouldn't have thought that they could score four goals, especially in the manner they did."
Stanley left-back Joe Maguire suffered a serious head injury during the first half and Coleman admitted that he was frustrated with how the game continued before then being stopped.
"It was a very nasty injury, it was a total accident, it's a cannonball of a shot that's hit him flush in the face, but I'm really annoyed that the game wasn't stopped immediately, that's very disappointing from a human being level."
Coleman's side now welcome Gillingham to the Wham Stadium on Saturday afternoon and he knows his team will have to be at their best to get something out of the game against Steve Evans' team.
"We have to go again on Saturday, there's no point feeling sorry for ourselves, it's happened and we have to learn from our mistakes.
"We'll work hard in training and we'll analyse Gillingham's strengths and weaknesses and then we go again like we always do.
"Every game is going to be tough in this league but we believe we can give other teams tough games ourselves like we proved tonight for a big part of the game."
