The controversial red card Rangers received in their Scottish Premiership victory at Tannadice this afternoon was because of a deliberate action, in the eyes of Nick Walsh.
The referee sent of Mohamed Diomande in the dying moments of the match, with Philippe Clement's side seeing out their 3-1 triumph.
The midfielder reacted angrily to a push by United defender Kevin Holt.
He appeared to raise his hand in the direction of Holt, however, video replays could not conclusively prove that any contact was made.
Clement has already revealed that the Ibrox club will appeal the on-field decision, which Walsh then stuck by despite VAR advising him to review the flashpoint at the pitchside monitor.

It's understood that Walsh believed Diomande acted in a deliberate manner, with a source at the Scottish FA suggesting the swing of the midfielder's arm was not negligible in Walsh's mind, hence why he felt it merited a red card for violent conduct.
Under Law 12 of IFAB's rules, the section reads: "In addition, a player who, when not challenging for the ball, deliberately strikes an opponent or any other person on the head or face with the hand or arm is guilty of violent conduct unless the force used was negligible."
