Sunderland boss Roy Keane blamed basic defensive errors as his side slipped to a disappointing 2-0 derby defeat at Newcastle United.
The Black Cats are still not mathematically certain of avoiding the drop after slumping to their second successive defeat, and Keane was far from happy with his side's display at St James' Park.
"I'm disappointed with the way we started and disappointed we couldn't get to half-time just 1-0 down.
"At this level you can't afford to give the goals away that we gave away.
"We made it very hard for ourselves, particularly with the second goal just before half-time. What we need to do is stop gifting teams goals.
"Newcastle will look at their first goal as a good goal but, from our point of view, we have ourselves to blame, it was poor.
"My players understood how important the game was. I'm not going to question my team's desire, we just gave away bad goals.
"In the second half, it would have been nice if we'd scored one to make it interesting but it wasn't to be. We've got a lot of hard work ahead and that hasn't changed. It makes next weekend that more important.
"I know they'll be disappointed but we have to bounce back. We've had a major setback today but we have to lick our wounds and come back next weekend."
