Danny Guthrie admitted he and his team-mates were left frustrated with the 0-0 draw against Nottingham Forest.
Rovers dominated the opening 45 minutes against Dougie Freedman's men but tired in the second half.
Guthrie, making his eighth start of the season in place of Corry Evans, impressed before being substituted just after the hour.
The point against Forest extended Rovers' unbeaten run to eight games whilst boss Paul Lambert is yet to taste defeat since taking over last month.
Speaking after the game, Guthrie felt Rovers needed to take advantage of their first-half dominance.
"We're slightly disappointed," he said.
"I thought in the first-half we were very good, but we probably needed to score whilst we were on top.
"If we did then I think we would have gone on to win the game comfortably.
"The second-half, they grew into the game a little bit, that was going to happen because they were a good side.
"But we've taken 11 points from a possible 15 and that is top six form."
