Sam Allardyce was critical of his West Ham side after they slumped to a 2-1 away defeat by Wigan at the DW Stadium.
Wigan were the better side and fully deserved their victory, but Allardyce instead chose to focus on his own players, who he said failed to take care of the ball properly.
The West Ham boss also felt that Wigan's first goal, a superb volley from defender Ivan Ramis, should not have stood.
"We never got going today, " Allardyce said.
"We never got to our level, never passed the ball properly and never stopped Wigan playing.
"The first goal was a great volley, I do think that there was push on Reidy (Winston Reid) for the first goal, but the referee didn't see it.
"It wasn't about Wigan for me today. It was about a lack of our ability to produce what we have got. It makes it difficult for us, because if you keep giving the ball back to them they use it well.
"Therefore the object of the exercise is to take care of it and don't give it back to them, and we didn't do it."
