Just caught the highlights.
First goal: White often fouls the keeper on corners but in that case I don't think it was. He established position in front of the keeper and just braced himself to stand there. He's entitled to keep his position if he wants and by the time the touch came he wasn't interfering with the keeper so no offside offense.
Second goal: As usual, the PL likes to complain about players diving but then repeatedly punishes them for staying on their feet. If Kulusevski goes down immediately, it's likely given either live or on VAR. But he tried to stay up so VAR doesn't give it.
Third goal: This one I think should have been given as a foul. He actually backed up into the keeper and threw him off balance. It's another case where players are punished for not flopping. If the keeper goes down when White backs into him there's an incredibly high chance the goal is waved off live. Instead he fought through it and gets zero benefit from it.
Spurs pen/second goal: Stonewall penalty. Laughable the ref didn't call it live.
The biggest thing we learn from the PL on nearly a weekly basis is that the best strategy is that if you feel *any* contact in the box you should immediately throw yourself to the ground. You will be rewarded for it far, far, far more often than not.
