Graham Alexander slammed the worst performance he had seen in 10 years as Fleetwood surrendered their Play-Off hopes in a 3-0 defeat to Rochdale.
Goals from Ian Henderson and then George Donnelly against his former employees put Dale on track for an important win. After Andy Mangan saw his spot-kick saved and then defender Nathan Pond was sent off for his involvement in a touchline altercation Jason Kennedy rubbed salt into wounds late on to leave Alexander fuming.
"We lacked inventiveness, competitiveness, energy, pride," he said. "We were bereft of any of that. For me that is the bottom of the barrel. There is not one positive I can take. For me it's the worst I've seen in 10 years.
"That was not football of a professional standard. I now have to make sure that never happens again."
Alexander's side dropped to tenth, but remain in touch with the play-off pack. But the manager was more concerned about changing the attitude within his side.
He said: "We needed good performances, there's one gone with nothing. We've got three left to show a bit of professional pride. We looked like we couldn't make it to the play-offs, or didn't want to."
Keith Hill was delighted with his side's progress - the result taking them further away from the drop zone.
He said: "I see a squad buying into the way the game can be played and we can be successful. There have been a lot of fights along the way, with the players to prove I'm right. As pleasing as we were on the eye, we were equally good off the ball.
"We've got the balance right at the minute. I'm pleased for the players, they've worked hard. They're being rewarded now.
"If we carry on with that hard work and energy we can deliver back to the football club and supporters what we achieved over our first four and a half years."
