Tottenham boss Ange Postecoglou says managers and players must do better with their behaviour towards referees.
Postecoglou includes himself in needing to improving his approach.
He told the Daily Mail: "Yes, 100 per cent. I was embarrassed for being booked (against Chelsea), even if it wasn't for abuse. It was for leaving the technical area.
"Anyone who has been in the game any length of time will tell you we have all experienced a bad decision something goes against us and also benefited from it. We have understood that's part of our game. That's the beauty of our game. There are flaws in it because we are dealing with human beings.
"If I take that another step back and think about the junior playground where young referees are trying to do it, what are they going to do and what are they going to see? 'There does need to be some addressing of behaviour along the way. It's easy for me to say but I have to live it and make sure I set that example.
"I am as competitive as anyone. I want to win. I hate it when a decision goes against me and it costs me a game. But at some point you have to respect the officials of the game. Otherwise, what's the point?"
