Think it's just about a pen.
But PGMOL are totally fucking VAR up by raising the bar for intervention higher and higher.
I'd bet the vast majority of VAR decisions that really upset fans are the missed overturns, not the ones that are given. That's why you hear "what's the point in VAR if it's not going to overturn that" a lot more often than "you can't overturn that, it's too subjective".
Just have the balls to call out every error, even if it embarrasses referees and takes a little longer.
The refereeing standard won't improve if the approach taken is "we can't overturn every big mistake, it'll make us look bad."
