Forest Green boss Mark Cooper was furious with referee Darren Drysdale after rock-bottom Stevenage held his promotion-chasing side to a goalless draw.
Cooper felt former Rovers striker Kurtis Guthrie should have been shown a straight red card for an aerial challenge on defender Farrend Rawson in the first half, with the Stevenage forward only booked.
Rawson failed to return after the break to leave Cooper incandescent with rage after losing Bournemouth loanee Kyle Taylor to a second yellow card four minutes from time.
He said: “If we are going to get a red card then Kurtis Guthrie should get one.
“The referee spoke to me before the game and made all the right noises and said: ‘I see you’ve had a lot of fouls against you.’
“I’m not going to get myself in trouble, but it’s clear for everyone in the stadium to see.
“I’m not particularly happy and we huffed and puffed. It was very frustrating and not a good performance and the only positive is we kept another clean sheet and didn’t get beaten.”
Cooper felt the long midweek trek to Carlisle took its toll on his side.
He added: “We had a long trip on Tuesday and looked really leggy and tired and we had too many players off their game, but fair play to Mark Sampson, Stevenage should be pleased with their performance.”
Caretaker boss Sampson felt Boro should have been out of sight, such was their dominance with a plethora of missed chances.
“We played well against a good Forest Green side and had opportunities to put the game to bed by half-time and could have pinched it at the death,” he said.
