No Players in 6 yard box

Watched Match of the day and he thought that Darren Englands decision was right if we appeal it what will it alter but another thing this Ex Referee said (I think his name was Michel Canns)was to stop all the fouls and pressuring the goal keepers when corners and long throw ins are being taken is to have no players in the 6 yard box I am sure Hermansen would be right up for this idea and it might stop all this controversy with VAR decisions it has already been said that Rice foul on Mavrapanos was a penalty, but the holding by Todbibo and the arm across Rayas face made the decision correct but what about the pen decision?? I also heard that Darren England is supposed to be refereeing the Fa cup, wonder if this will still stand after the appeal
