All season? Arsenal started this long long time now. Officials had accepted it as legal, in the process more teams followed, not as effectively as Arsenal though. They, Arsenal, are the ones who possess the expertise. Basically they have invented this "strategy", among similar others, of course. Anything that will suit Arteta's vanity...
Since it's gone too far, now officials seem to be having second thoughts about it. I remember the Bornmouth equalizer, earlier this season. I grew up knowing this shit does not exist in football. Nevertheless it stood. So what they do? They start cancelling goals. It happened in one of our games recently (remember which one?), with Pep ironically commenting afterwards: "Today I broke another record"...
The approach remains highly selective though, as we have just witnessed tonight. The player who is supposed to be fouling the GK, look at what he's dealing with, as he's trying to position himself towards the ball. Look at other WH players running in the box, what they're also dealing with. From all this chaos, England decided to isolate THAT moment, and make his interpretation of it...
VAR was introduced to guarantee justice supposedly. Refs could not handle the pace of the game anymore, their mistakes were inevitable. But officials do not want justice. It's not about fucking justice, justice is not the objective, never was. So VAR becomes another tool to manipulate results at will...
