I think today was a perfect example of VAR is useless because of the people in charge.
Foul on Saka should have been a red. How that hasn't met the threshold, despite being just below the knee and a potential leg breaker is astonishing.
The penalty is a dive. Havertz initiated contact.
The goal, a little hand on the keeper, but it's not a foul.
All three should have been changed, with potentially the ref going to the screen. All were not changed because it wasn't 'clear and obvious'. I think most of the footballing world disagrees because all three were the wrong decision.
