Sunderland boss Steve Bruce is still struggling to contain his anger at their defeat at former club Wigan.
The Black Cats headed for the DW Stadium riding high after their 1-0 victory over Arsenal to meet a side which had just been trounced 9-1 by Tottenham.
However, it was Roberto Martinez's men who came out on top to leave Bruce reflecting on a fifth defeat in seven Barclays Premier League games away from home.
He told the Sunderland Echo: "I can't stomach the sort of performance we saw at Wigan, like the one we saw at Birmingham or for much of the game at Burnley, because those results end up catching up with you.
"This is the frustrating part of it - the fact that we could have been doing so much better if we had just turned in a half-decent performance in some of these games. We would be a lot better off points wise."
Hugo Rodallega's lone strike was enough to hand Wigan all three points last weekend as Sunderland once again failed to turn up in an away game.
Bruce added: "I don't often get angry, but I was on Saturday and in all honesty, I'm not in much of a better mood now when I think of the game.
I'm still struggling to hide my disappointment.
"Defeats are part and parcel of football, so it's got nothing to do with that, or with the game being against my old club - it's all about how poorly we performed on the day.
"I have always said I don't mind us losing so long as we lose 'with our boots on', as long as you turn up and you have a right good crack at the opposition."
