Careful, you’ll have ArsenalMania telling you that there is no such thing as VAR bias and its simply an excuse.
I think the concept of VAR is pretty stupid, personally I don't think the point of football is to get everything correct. But right now it's often not the technology that's the problem, it's the people using the technology.
So VAR may not be the problem, it could be the same old problem that referees subconsciously view Arsenal as a soft touch.
Who knows, maybe next season there'll be completely different results, but right now it looks like VAR hasn't treated Arsenal too well.
