That's such stupid business sense. If money is the defining factor in a players decision under the age of 26/27, then we don't want them anyway. If they're older and looking for a last big payday, then we don't want them anyway.
Take away the rivalry and hate towards Liverpool and they would be my second choice behind City if I was a younger player (22-26) with Dortmund as a very close third choice (who would probably be first choice if I was 18-22). Purely based on playing style, managers and career development - money wouldn't even come into it. Look after your career development and the money will look after itself.
