Grant McCann is determined to get to the bottom of the disparity between performances at Rovers this season.
McCann was frustrated by the manner of the showing against league leaders Stockport County, who cruised to a 5-1 triumph at the Eco-Power Stadium.
The Rovers manager admitted to being baffled by the dip in performance level from the win over Wigan Athletic in the Bristol Street Motors Trophy.
"It's been a theme of the season - we can be so good one game and then drop massively in the next," he said.
"We were so good against Wigan in the second half of the last game and then we dropped to these levels.
"I don't know why. Myself and the staff are questioning what the week leading up was like. We felt it was really good and probably one of the best we've had this season with players coming back from injury, a behind-closed-doors game and getting a breather into a few of the lads as well.
"I actually don't know myself and I can't put my finger on exactly why we looked so lethargic and so slow out of the blocks. We just never gave ourselves an opportunity with the way we conceded the goals and we looked toothless as well.
"We don't give ourselves any hope or chance conceding the way we did and it looked like it knocked us once we conceded the second and the third.
"Stockport are a really good team, they're top of the league but we've given them three goals in the first half.
"There's a lot for us to digest and look at from this game and we need to put it right at Bradford on Tuesday in the quarter-finals of the Trophy."
