Oldham boss Paul Dickov blasted his players for ignoring his pre-match instructions after they were crushed 5-0 by MK Dons.
Dean Bowditch's penalty had given the Dons a slender half-time lead, before Daniel Powell's double and further strikes from Mathias Doumbe and Stephen Gleeson emphatically sealed their first win in six games.
"I'll start by apologising to the fans who came down, it just wasn't good enough," said Dickov. "If people don't want to take on board what we tell them to do and what we work on from Monday to Friday and they think they can go out on a Saturday and do what they want, then they won't have a career in football.
"Sometimes people want to go out there and they think they are better than what they are and that was the case. If you don't do your jobs properly against a good team, and I think MK are the best team in the division, then you're not going to win the game.
"There's 1,200 players out of contract in the summer and a lot of them in there think they're good enough to go and get another club - on that performance I would doubt that."
Dickov has been linked with the vacant managerial position at Huddersfield but he admitted this result will have harmed his chances, saying "I won't be odds-on favourite now!"
