Karl Robinson has described referee David Webb's performance during MK Dons' 2-1 loss to Leeds United as "atrocious".
Samir Carruthers was sent off in the 78th minute and Robinson thought that Leeds player Luke Murphy should also have been given his marching orders.
"The refereeing was atrocious," Robinson told BBC Sport. "We've played here and we've been the better team. Someone has to say something.
"He should have to tell you why he sent Samir Carruthers off. Then two and-a-half minutes later Murphy has a scissor challenge on the 'D', and there's no booking, and it's his eighth challenge of the game.
"We ask for consistency, and integrity, which they give us all the time, but the performance was way below par today I think from the referee."
MK Dons are just one point above the relegation zone in the Championship table.
