Andy Butler says his players didn’t get the basics right in the defeat to Bristol Rovers in Sky Bet League One.
Rovers were beaten 2-1 at the Memorial Ground, despite James Coppinger’s early opener on Easter Monday.
He said: “We started the game well and deservedly took the lead, but then we stopped doing the right things and let Bristol Rovers back into the game.
“I’m disappointed and frustrated, we knew they were low in confidence and felt if we started well then we could hurt them.
“People know that I demand hard work on and off the ball, and that is something I’ve got to address after that performance.”
Despite the result, Butler says he is determined to work with the players to find a way through their current form.
He added: “I will never question the players’ hunger, I don’t mind mistakes as long as there is a reaction to it but we’re not getting that at present.
“They are all professional footballers who are paid to represent this football club, anything I say will be kept in house and there will be points put across to the whole group.
“I still see the same players that were performing well not so long ago, and I think they are giving everything for me as I would for them if it was the other way around.”
