Grealish doesn’t dive?!?! Christ, he’s incessant.

He even dived when that Brum fan slapped him. If, when a player goes down, he gets both feet off the ground at the same time; he’s diving.
I suspect that you’re under 30, FFB, possibly nearer 20. Neither Grealish nor Hazard, have never been subject to a proper foul in their careers. In a contact sport, those two twats feel the slightest contact and go down.
I’ve seen worse players, get hit with more robust challenges and stay on their feet. Have a look on YouTube for Strachan v. Uruguay.
He has all the skill and vision to be a great player and yet relies upon shithousery. Bielsa once said something along the lines of ‘think about what kind of football we are passing on to the next generation’. Grealish in totality doesn’t represent something I’d want to pass on to the next generation and be seen as acceptable.
