Salmon always was an opportunistic w*nk.
I'm not sure that's correct, but even if it is the use of VAR or any similar system was always going to be sh*te and any changes to it won't improve it significantly IMO.
The very people who were crying out for something like VAR are those who are now criticising it most. It perpetuates the narrative that keeps them in a job/gets them likes on Twitter (as was), that "referees are sh*te".
