steups dey was digging at hazard whole time so it ok to cynically kick dong ah man whole game den?
Easy hero.
Let's deal with specifics, namely the two yellows on Herrera. For the first yellow, it's debatable that it was even a foul. Herrera is under no obligation to get out of Hazard's way... he's just prohibited from deliberately obstructing the attacking player. Hazard kicked the ball past Herrera who seeing the impending collision a) did nothing to get out of the way (that's the optimistic view); b) Braced himself for the collision (the pessimistic view). He made zero movement into Hazard's path. Not a foul.
Even if you want to argue it was a foul... it was hardly a yellow card worthy foul... but let's grant Oliver the benefit of the doubt on that one.
On the second yellow... straight up comedy. The view taken by the commentators was that Oliver had just warned Smalling that the next player to foul Hazard was going into the book. This is outrageous, if true. Not only was he putting an effective bubble around a specific player, but doing so with more than half the match still to be played. That's not even the most outrageous part... the most outrageous part is that he's pre-determined in his own mind that he's going to show a yellow card for the next foul, no matter the severity of the infringement. That's shocking... again, if true. Individual players can be booked for persistent fouling, but I don't know of a provision that allows a player to be booked for persistent fouls committed by his team.
If that's NOT the reason why Herrera was booked, that he was shown a second yellow for his own actions and not those of his team collectively, then that's a poor yellow on it's own... and a ridiculous second yellow to show. Hazard was more than happy to go down, he turned and looked at the ref before he even stopped rolling on the floor. Even if Oliver deemed it a foul... to give a yellow, let alone a second yellow? Nah.
And look... with Mourinho and Manchester United it's like Satan coaching The Evil Empire, I have no reason to defend them. I don't like Chelsea, but not as much as I dislike Manchester United or anything related to Mourinho.
