I agree, with the caveat that generally football supporters project a lot of care/interest/passion onto footballers. The vast majority of these guys don't actually give a shit, they're just making money and want to make as much of it as possible.
They're not all BAE's, but the average footballer is closer to that end of the spectrum than we'd care to think about.
Most players that reach Eze's level, as well, would back themselves to earn a spot. Similar to Dier repeatedly backing himself to win over another manager, and he was right all the way up to the last one.
Either way, in Eze's case the smarter move would probably be Spurs unless City are offering 150%+ on the wages. Certainly more available minutes, London shits on Manchester, and if he grows into a world class player we'll certainly sell him on to Madrid where he can collect gross wages and pile on the silverware in the sun.
