Do not see why Mount gets so much hate. Would love to see a young player like that at United. I think it is more the media perception that someone like Grealish is dealt with harshly as he is just as hard-working as a Mount but also naturally more gifted.
Not aware of any "hate" directed at Mount but get your drift. To be honest I have my reservations. He has been known to drift out of games and not have an impact. He always gives 100% but doesn't always catch the eye whereas Grealish may have slightly silkier skills.
For me he doesn't get in Chelsea's first 11 if Pulisic is fit.
His work rate in the high press is second to none and this makes him a managers dream. As a manager myself I recognize the positives in using somebody who has a terrific work ethic. Its better to have a really hard worker who does what you ask rather than a highly skilled one who only does so intermittently.
As that beacon of morality Woody Allen once said, "80% of success is turning up".
