Paul Lambert believes decision making in the final third is proving costly at the minute.
Rovers slipped to a third defeat in a row on Saturday as they went down 1-0 at Cardiff City.
The Rovers boss feels that the team are getting into promising positions, but they aren't making the most of them.
"You've got to just keep having the confidence to go and really pull the trigger in the last third," said Lambert.
"We never curtail anybody, they've got the freedom to go and make things happen and that is where decision making comes into play. If you get into good areas then it is about the right decision making.
"It isn't as if we aren't getting up there and thinking where do we go next? It is poor decision making that is costing us at the minute. We are getting into good areas but it is not just quite there."
With the opening of the January transfer window on Saturday Lambert is keen to add to his attacking options, and will look to bring more creativity to the squad.
"We certainly need help on that front," he admitted.
"I said when I came in that I wasn't going to make excuses about the embargo or anything like that but we've not been good enough in the last three games to win games.
"Against Cardiff it is a little different, I don't think we deserved to lose this one.
"But I think if we can get a little bit of help somewhere then we'll certainly try and do it.
"We certainly need a shake-up, it is there for everybody to see. I'm not going to kid anyone and say it is a bed of roses, we need reinforces to help."
