So from what I can see here.
1. The United player has absolutely no chance to shoot, so not comparable to Phil who had an opportunity.
2. The United player slowed down leading up to the ball unlike Phil who was at top speed running towards it.
3. The United players pass nutmegs the Liverpool defender (which is pretty lucky), and he had 3 options in the box, unlike Phil who had one.
This is just getting embarrassing from this forum honestly.
Phil in an instant has to pick between 2 valid options, and perhaps picked the wrong one, but given how often he scores from the left and the fact that it's on, and considering I can see him thinking he can't make the pass come off... I'm thinking yeah, let's back the fuck off him for this action.
