Gary Bowyer was far from happy after Rovers slipped to a 3-1 loss to Ipswich Town on Tuesday night.
Rovers had done well to battle back from the disappointment of an early Luke Hyam strike, Jordan Rhodes levelling on the half hour.
But as has so often been the case on their travels this season, Rovers proceeded to shoot themselves in the foot with two further poor goals conceded.
"We have got to stop giving goals away to the opposition, it is as simple as that," said an angry Gary Bowyer after the game.
"We started well, DJ could have scored, and we looked like a good team.
"But then there's a chance for quite a few of ours to block their shot and we don't.
"We recover well, play some good stuff, get a great goal, and we were the better team and had a couple of more chances.
"At half time you think there is only one side that is going to win it, but unfortunately games aren't won at half time.
"Then we don't track a runner, we don't clear our lines, the lad has time to fall over it and still has time to put it in the back of the net. It isn't acceptable.
"It has got to come down to our mentality, we have got to be tougher and horrible to play against away from home.
"We have to cut out the individual mistakes, because in possession the chances that we create look good.
"Tonight was not acceptable in terms of goals that we have given away."
