Don't be so facetious, they're obviously gonna be a bigger and better Chelsea so obviously plenty of players are gonna be interested in that in this day and age. It's not as though United's players are all there because of the history and that's all they care about, far from it.
City could conceivably win the title this season, they're 3rd at the moment and brought in some good players, and if they can keep things going 'til January - far from impossible, they could splash loads of money and then mop up in the 2nd half of the seaon.
