MARK CLATTENBURG: Brighton's players were right to feel angry with Lee Mason after the free-kick fiasco that saw Lewis Dunk's goal ruled out... it was a lack of concentration from the referee

Back in 2017, I was refereeing Liverpool against Chelsea and David Luiz asked me if he could take a quick free kick. Fine by me.

I’d measured the defensive wall, making sure it was 9.15 metres back, and the game was ready to restart so I blew my whistle.

Luiz took the free kick, scored and Simon Mingolet was blamed for not being ready. Once a referee has measured the defensive wall, he can restart play by blowing his whistle.

It’s down to the goalkeeper to be ready - not for everyone else to wait.
