For me, Saturday was a landmark relating to my opinion of Premier League referees. Up to now, I have been unsure as to whether the majority of them were simply incompetent, or corrupt. Now, I know. Paul Tierney was most certainly incompetent and possibly corrupt. Craig Pawson, the VAR, was most definitely corrupt, by his complete failure to overrule the many mistakes made by Tierney, when he had the benefit of watching video replays from different angles.
It really is pointless in having referees as VAR, since they won't want to expose their mates' mistakes during a match. It needs trained analysts to be VARs, who are from a totally different group to Mike Riley's bunch of crooks and cowards (Anthony Taylor excepted).
