Tony Mowbray pulled no punches in his assessment of Rovers' performance after they went down 1-0 to Bury in their latest Checkatrade Trophy group match.
Rovers went into the match looking to build on their victory over Stoke City in the previous group match, but were undone by a late Shakers goal from Harry Bunn.
The manager felt there may have been a foul on goalkeeper Andy Fisher in the process of the goal being scored, but that wasn't excusing what he called an 'insipid performance'.
"I thought it was poor to be honest," said Mowbray after the match.
"If there were any positives then the young boys at the back did alright, stuck to their jobs.
"The goal looked like it was kicked out of the goalies hands but I haven't watched it back yet. But there wasn't a lot to be positive about.
"I have to take some responsibility, throwing a team together without doing any work on it.
"They looked as if they didn't have any direction of where to go or how to play. Many of the lads haven't played very much this year and then some of boys from the Under-23s, so it looked a very disjointed performance.
"We struggled to play forwards, we struggled to create anything, it was really poor, it was disappointing.
"Individually there was a lot of quality out there, a lot of footballers who should have damaged Bury more than they did. But it was an insipid performance, no threat, no goal threat or urgency.
"I expect better and I hope they do. The players know my thoughts and we move on."
