Former Premier League ref Mark Halsey says Howard Webb needs to be withdrawn from the frontline.
Halsey told talkSPORT: "Howard has made an error of judgment. He has not had the best of seasons. He has not been the Howard Webb we all know.
"Perhaps he may need a little rest because he is perhaps doing too much.
"He is not just refereeing football matches, he is doing a lot of work outside of football. He is doing a lot of after-dinner speaking. Everyone wants Howard Webb because he was the World Cup [final] referee [in 2010].
"He has to take a good look at himself in the mirror and ask himself what he wants. This (refereeing) is his full-time job and he has got to concentrate on this.
"He has to forget about what he is doing outside of football. He has got to put that on the back-burner and concentrate on what he is being paid for full-time."
