Swansea City manager Garry Monk said his players put in the worst display he had seen for some time as they lost 3-1 at West Ham United.
Wilfried Bony had given the Swans the lead, but Andy Carroll scored a brace to turn it around and, after Swans keeper Lukasz Fabianski was red card, Diafra Sakho added a third.
"I just don't think we ever reached the levels we have done this season," he said. "That is the first time I can say that, in all the games we have played. We did not make enough correct decisions. The only time we did that we scored the goal.
"We didn't do that enough and really some of the defending, we gifted it to them on a plate to be honest. No complaints with the result, we didn't deserve anything from the game.
"We actually had our best spell when we went down to 10 men but it shouldn't take a situation like that for us to play our best football. We gave them an early Christmas present I think."
Monk also confirmed he would be considering an appeal against Fabianski's dismissal having spotted an infringement by Sakho in the build-up.
"If you look at the build-up to it, he knocks the ball past the keeper with his hand," he added. "I don't think we dealt with the situation leading up to that point very well but before Fabianski makes any contact whatsoever, the player knocks it past with his left hand.
"Realistically it should have been a free kick to us. It wasn't a clear goalscoring opportunity either -- when you look at it with the replays, it isn't [a red card]. Hopefully we will appeal it."
