Stoke boss Tony Pulis has described imaginary card-waving from managers and players as "unacceptable" and called for it to be eradicated from the game.
Manchester United striker Wayne Rooney and Manchester City manager Roberto Mancini, in particular, have hit the headlines of late for their actions during recent matches.
Mancini described his gesticulation during his side's 1-0 win at Wigan on Monday as "normal", after Wigan's Maynor Figueroa deliberately handled, denying Sergio Aguero a run on goal.
However, such actions could be deemed as unprofessional, and disrespectful towards any referee.
Pulis pulled no punches with his thoughts on the subject as he said: "It's something that's come into the game that should be stopped, and the sooner the FA do that the better. Sadly, it's the way it's gone, and for me it's unacceptable.
"Let the referee officiate and decide whether it's a yellow, red card or a fair challenge, and the rest of us get on with it."
