Neil Warnock felt his side led to their own downfall after poor defending gave Southampton a comfortable lead in the 3-1 home defeat.
"You can't concede goals like that, defending well and breaking has been our strength this season but the goals are all very poor,
"Individually it's not for me to say on record but I've told people in the dressing room what I feel about the goals, we've got to eliminate the mistakes.
"With all respect to them, it wasn't Southampton's fantastic play, it was the defensive side of our game that needs re-tuning.
"The players know what I feel. We need everyone to be on top of their game. The goals are so poor. If I was a player today I'd blame the manager, it's always easy to do that."
Discontent from the stands during the game was not a surprise to Neil and post match he said that after any defeat the manager must be the one who looks for the answers.
"When you lose a game you're responsible as manager, I've no complaints about that.
"You know when you take Bolasie off when you're losing 3-0 you're going to get stick, but you just have to think about our next match.
"Bolasie's wife is having a baby and he was tired before the game today. What with us playing at QPR in not much more than 24 hours, I thought we would just save his legs a bit.
"I have no complaints, at 3-0 down, you'd be very surprised not to get a bit of stick.
"I thought the players were very good today in the circumstances, they were almost as shell-shocked as some of the fans."
Away from the busy schedule of fixtures work continues ready for the transfer window opening.
"We've made offers for three strikers as I speak. We know we're not going to get them all, the chairman is dealing with it, he knows more than me about how close we are."
