Swindon's caretaker boss Tommy Wright, who has been placed in charge until the end of the season, was not impressed with this side's performance, and said it was "a very tame way to get relegated".
"It was always going to be an uphill battle to stay up, but to go down like that, with not a lot of pride and not a lot of effort - it could have been 10," he said.
"They were good, but we were so placid for the first 25 minutes.
"I'm really disappointed with the way we played. To go down like that, we need to look at ourselves - it's just not good enough, really.
"You're playing against a good team, and you might get beat, but get beat in a manner that you can show to the people of Swindon that we're going to fight all the way.
"It was like we accepted we were going to go down - it's not acceptable, really."
