Manager Darren Ferguson is expecting a reaction from his players after seeing his side go down 1-0 away at Charlton Athletic.
Tariqe Fosu’s ninth-minute goal at The Valley was all that the Addicks’ needed to claim all three points, despite constant pressure from Rovers in the second half.
“It’s an unacceptable result, the first half was nowhere near the required standard and we’ve lost a poor goal which has cost us the game,” Ferguson said.
“I won’t criticise individual players but it’s a clear mistake by someone, it’s a poor goal to concede we’ve been too slow and the tempo wasn’t there and we weren’t quick enough.
“They have to take responsibility themselves, but as the manager, I have to as well, but there’s only so much I can do.”
Ferguson was also left to rue missed opportunities, with Rovers having plenty of chances to get back in to the game, but Karl Robinson’s men did enough to cling onto all three points.
“If we played in the first half like we did in the second, we win the game, but we’ve been careless and there were too many mistakes,” Ferguson said.
“The reaction after half time was good but the early goal has meant that they’re hanging on, they’ve been restricted to opportunities to counter attack because of us chasing the game, but the results just aren’t going our way.
“Alfie’s hit the bar in the first and Tommy should score in the second half, it’s frustrating because there were parts where it was good, but we need to kick on because clearly it’s a big week coming up and we need a result on Tuesday night.”
