Call me bonkers but I do believe we should use foreign referees in the Premier league in the future.
The Premier league should be looking for strong refs which can't be easily influenced across the globe. They should be well payed to attract them and even flown in and out from there country per game.
I personally believe English referees have an unquestionable bias towards certian teams. And even fear making the right decisions against the top teams as fan backlash on social media scares them. Whenever a controversial moment happens in a game with any of the big teams(scum 6) the spotlight on the decision is insane and they fear fan backlash in real life(death threats) . I mean the fans from the scum 6 are the overwhelming majority of fans and they pile in whenever they feel wrong and it's hard to even see right and wrong sometimes when an overwhelming bias is at large.
Returning to the original idea I believe referees from abroad would be partially immune from this. As they wouldn't see your local dickhead scum 6 fan out whilst shopping if they flew in and out. Also another thing to take into account is English referee's integrity and who they really support or where they are from I also think this is fixed as most foreign referees won't have serious loyalties.
