It's at this point they could have just checked what they're actually checking, and cleared up the comms:
And then at this point they could have paused the game, merely a few seconds (if that!) after the restart. Yes, Spurs would have argued that the game restarted so should have carried on, but if you're looking at the integrity of the game to clear up a 'clear and obvious error', then go back and give the goal:
Then, weirdly, the replay operator confirms 'are you happy with this?'. Even weirder, is that the Assistant Ref says 'yeah, offside, goal, yeah'. SO CLEAR, lads. FFS.
Then the PGMOL Hub Ops chimes in way too late, asking to 'delay'.
This is the most frustrating thing - 'Can't do anything'. Yes. Yes you can. Stop the game. Take some initiative.
Simon Hooper isn't to blame here, and he's been majorly let down by his assistants on the pitch and in VAR. How he wasn't communicated with at any point is beyond me.
