Rochdale manager Keith Hill accused his players of going missing as their run of six successive league wins was halted in a comprehensive 3-0 defeat at Swindon.
First-half strikes form Darnell Furlong and Nathan Delfouneso put Swindon in command, only for Dale striker Ian Henderson to waste a chance from the penalty spot to bring his side back in to the game, and Joseph Bunney was needlessly sent off before Nathan Thompson sealed Swindon's victory.
Hill said; "The run was always going to end at some time but we didn't turn up. I don't know if it was a hangover from Saturday but we knew what we had to do against Swindon and we didn't do it.
"To be honest, they could have scored more than two in the first half and we didn't take responsibility for closing down and all the things we usually do.
"It took us to half-time and the changes I made for us to get back into the game."
Bunney was sent off by referee Gavin Ward for an off-the-ball tangle with Furlong, an incident which left Hill confused.
"I don't want to say too much as I am going to see the referee," he added.
"I really don't know why he sent him off. We could have finished with fewer than 10 men as there were so many players getting yellow cards for nothing."
The result not only moved Swindon up to 17th in the table but relieved some of the pressure on head coach Luke Williams, who has been the subject of intense criticism on social media.
Williams said: "I don't see a lot of the stick because I don't really follow social media but people have told me about it.
"I prefer to have the criticism on me rather than on the players. I'm not the the type of person who celebrates too much when we win, nor do I get too down if we lose, and if that's not the type of person people want me to be then I'm sorry.
"I'm really pleased for the players and they deserved this win. It was the result of hard work and concentration..
"That's two successive clean sheets and I think we're coming to terms with things and we went a step further with this win against a very good team.
"I'm sure some people will say Rochdale were below par but I think we were very good at making it difficult for them."
