Derby County boss Wayne Rooney blew a fuse after defeat to Swansea City on Saturday.
The Rams are second-bottom in the league and nine points from safety with just five matches remaining.
Rooney lost his cool over what he believes was a blatant penalty denied to Derby in the late stages of the Swansea match when his side were desperately chasing an equaliser.
Derby substitute Bartosz Cybulski was clattered into in the box while competing for a rebound, and the Rams players all appealed. Ref Tim Robinson, however, was unmoved.
"I think everyone in the stadium agrees (it was a penalty), the Swansea manager, the Swansea staff, the Swansea fans, Derby players, staff, fans, everyone saw it was a clear penalty apart from the four officials," Rooney said.
"I have said it time and time again. I understand it is difficult to give it when it is a tight one.
"When it is a clear obvious foul and penalty it leaves a lot of questions I have to ask the officials. I hope the referee gets banned and fined because that is not good enough."
