He'll lose his job and rightly so as it's unprofessional to make comments like that.
I do think fans make more of this kind of thing than is realistic though. If a referee is professional then who gives a **** whether they like your club or not? Do all doctors like their patients or all solicitors like the clients they are being paid to represent? Nope. They're doing a job to the best of their ability.
Fans like to claim corruption and favouratism as it suits the childish "woe is me" understanding of the world - like pupil who get told off by a teacher "because they hate me" rather than because of their behaviour - when in reality referees just make mistakes as they're human beings. Do big clubs get more decisions? Probably yes, but there's a variety of reasons for that and referee corruption i don't think is one of them.
ps. Does anyone actually disagree with anything the guy said?
Reality - refs are human
Further - there has always been a bias towards the big teams - remember us getting a pen at Old Trafford in the Martin O'Neil era and the commentator saying how many matches it had been since an away team had last been awarded one there ... it was seasons ... but the refs were definitely intimidated by SAF... not on the same level perhaps but Klopp, Wenger and Mourinho would all have had refs thinking they were ****s...
... but do I think any top refs start a match with intentional bias ... no I don't.
