Alas we're digressing, to answer your question imo Hazard right now would chose United, Arsenal, Liverpool, Chelsea & City all over Spurs at the moment. That said I also think he'd chose Real Madrid over any team in the PL also.
You seem to forget DM, money speaks.
Pretty damn sure no one said he'd go to Arsenal or Pool over Spurs neither.
Also, money speaks but, lets say at Lyon he's lucky to be on 40k a week, sure City can offer 150k a week, though they still might not, remember FFP is coming in and people aren't really looking to add huge wages on till they know how FFP will shake out, but 100k a week at Arsenal, 70k a week at Spurs maybe, 100k a week at Barca.
Be honest, would you even give a crap? He's already rich, he'll finish his career stonking rich, and don't forget players make as much again, if not a lot more in some cases via sponsorship deals, those will be worth more, the more he's playing and the more he's scoring.
I mean affelay isn't a bad example, maybe not rated quite as highly, but another player with the potential to be world class did go to Barca, and barely gets played, had he gone to say Spurs, he'd get a crapload more games, more experience, more goals, more advertising money and the chance to move to a "bigger" team like Barca as a 30mil star who would play first team, rather than a "youngster" who is seen as for the future and barely playing.
How much is enough, numbers talk but only so much, City may have offered big money to some of Arsenal's players, and others, but they also offered a VERY obvious very real title fight very soon. People joining City 3 years ago knew exactly where the team was heading.
Money's great, but realistically if you earn 50k a week or 250k, you'll probably lead an identical life buying the same stuff and just have a bigger balance when you die.
