Walton wrote in The Times: "Football as a sport has been asking for this for quite some time now. When something like this happens, it puts ideas in people’s heads. Fans, managers, club officials, this has planted the seed, and almost granted a vitriolic licence for others to follow suit."
He added: "In that respect, the timing couldn’t be better. This country is having a reckoning with the abuse of officials and maybe this can be a jumping off point to make meaningful change... Officials need to feel supported at a time like this. Then, maybe the likes of Jürgen Klopp and Mikel Arteta will think twice next time they rush to harangue an official or question his impartiality after the game and incite pile-ons.
"However, words and statements only get you so far. The real truth is that we need to be much harsher in terms of the punishments we dish out. Only then might we see some real change.
"I look at Arteta serving a touchline ban the other day — all he has to do is sit up in the stands instead, shaking hands with everyone. Is that enough of a punishment? I don’t think it is. We need longer bans, points deductions, managers should not be allowed to come to the stadium on match days. These sorts of deterrents send a message, that any form of abuse to officials is wrong and will not be tolerated."
