Was never sure how they selected the absolute correct frame for the offside lines. Appears VAR peops weren't too sure either as this season there is apparently a 'tolerance level'. Presumed that was why MR goal stood as he looked offside in pic that was flashed up on tv. Not sure what they pay the commentators and pundits for sometimes as they did not mention tolerance change or explain that the goal would (most probably) have been ruled out last season.
But then they didn't explain to the tv audience why Palace fans were booing Partey throughout the opening match either!
