Michael Duff was left disappointed by the refereeing decisions that proved costly to his Cheltenham Town side in the opening day defeat at Leyton Orient.
Referee Michael Salisbury showed two red cards to Robins players Luke Varney and Rohan Ince, while also turned down what appeared to be a clear penalty in the early stages of the game.
Josh Wright's second half goal was enough to help Orient seal their return to the Football League with a win on day one, on what was an emotional matchday at the Breyer Group Stadium.
"It was a stonewall penalty," Duff said post-match. "He's booked Reg (Luke Varney) as well which has led to a red card later in the game. I didn't think it was a yellow card either. I've got to be careful but I don't think we got any help from the referee today.
"I thought we started the game really well, got on top, and to go 1-0 up to kill the atmosphere if you score the penalty of course would have been a big marker straight away.
"You can only hope they make the right decisions and I don't think he has."
