Mathieu Baudry says the players must take responsibility for the 3-0 defeat against Walsall at the Keepmoat Stadium.
Rovers conceded three goals after the break which condemned them to defeat and ended a run of two league wins in a row on home soil.
Baudry said: “The boys have been talking in the dressing room, we take full responsibility for the result and that type of thing shouldn’t be happening.
“The manager is disappointed, we let him down because we didn’t show what we’re capable of and he always puts his trust in us.
“We really want to play well for the manager, who is the best manager I have worked with, and repay the faith he has in us.”
Rovers did all the pressing in the first half against the Saddlers without finding a breakthrough, and Baudry believes they must be more clinical in front of goal.
“I think we looked comfortable in the first half but we couldn’t step it up and get that first goal which was always going to be important,” he added.
“We had a lot of the ball but could not break them down so we exposed ourselves on the counter attack and they took advantage of that.
“We were on top without playing that well before the first goal but that’s not good enough to be able to beat teams in this division.”
