Sir Alex Ferguson offered no excuses after his Manchester United side were upset by Norwich at Carrow Road.
Anthony Pilkington's second-half header condemned United - missing the ill Wayne Rooney - to a first league defeat since September.
Ferguson said: "We're disappointed to lose the game but we have to give credit to Norwich for the way they fought and battled for every ball on the pitch.
"They defended fantastically well and the goalkeeper also had a really good night so it's disappointing.
"It was a marvellous cross and a marvellous touch for their goal so our goalkeeper could do nothing about that. They deserved the win just because they worked so hard for it.
"The players are used to making comebacks and we're always a threat in the last minutes of matches. We had a lot of half-chances but it just wasn't our night."
Rooney was out with tonsilitis, and Ferguson said: "We always miss our good players but we had plenty of good players on the pitch."
Adebayo Akinfenwa bagged a goal in each half, the second coming from the penalty spot, to move to 12 for the season .
Chris Hackett added a third goal before Joel Grant reduced the arrears from the penalty spot for a Wycombe team that held their own for long periods but slipped to the bottom of the table.
Boothroyd said: "I was pleased with our first half performance, we dominated the game and deserved to be a couple of goals up, but not our second half display. We made some daft decisions on the ball in the second half and we looked mentally tired at the end.
"Obviously, I'm pleased we've got the three points but I've told the players that the second half performance wasn't good enough. On another day that would have ended up a draw if we hadn't been so clinical in front of goal.
"We've had some long trips recently but I can't use that as an excuse, it's the same for all clubs in this league. At least we dug in, weathered the storm and got the result.
Keith Lowe opened the scoring just seconds into the match and Chris Zebroski continued his recent goalscoring form with another striker but Rotherham scored four times to end the Robins' four game unbeaten run.
"We had to chase the game," Yates said. "We needed to stand up because we knew there would be a backlash from Rotherham. It was far from pleasing, but the good thing is we have another game on Tuesday.
"There was a lot I wasn't happy with today. There weren't too many positives to come out of the game. Keith Lowe was outstanding but apart from that I don't think too many got any positives out of the game and that's disappointing.
"The subs came on and livened it up but we knew we had to stand up and be counted and today we didn't in aspects we are quite good at and pride ourselves in.
"We played some decent football but if you give teams goals and look wide open you are going to get caught. It was far from pleasing."
The game had appeared set for a draw after Shrimps substitute Jack Redshaw cancelled out Lewis Montrose's first-half opener.
"To get beaten in that manner in injury time after the work rate we put in was devastating," said Bentley. "We played some good stuff. The substitutions worked well, and Jack put the ball in practically with his first touch
"But after that they threw a lot at us, but we defended our set plays well and when we did get the ball we soaked up the pressure and worked one or two very good chances. It can happen and when you switch off for a second you can get punished, which is what happened for both goals.
"We gave a very good account of ourselves and I hope it doesn't take the wind out of our sails as we've been playing really well of late.
"Although we've got a small squad for this level we really pushed and almost made it count. I'm really sorry for the fans who made such a long journey down here something to shout about."
The Pirates took the lead though David Clarkson's spot-kick after Peter Cavanagh's trip on the same player.
Goals from Andrew Tutte and Bobby Grant turned the game on its head before Gary Kenneth and substitute Eliot Richards saw red in the second half but McGhee insisted it wasn't all bad news.
"We have to take more of our chances and defend better set-pieces better, but I think we're working hard enough," he said. "There was a lot of spirit put into the performance, we have just got to keep doing that and we'll be okay.
"We lost this game but there were a lot of good individual performances.
"We were horribly indisciplined for the two sendings off, and while losing the game was the worst thing, having the two players sent off in such circumstances was very disappointing."
