anyone would ask for that in his situation. United couldnt afford to lose him as that would be a bad image for them, and they would be unable to attract big names (bad season, selling best players, completely changing the team) so i think, appart form a few loyal players in this world, anyone would try to get as much as he can...
Arsenal most likely is out of the title race. City (if they win the -2 games) will be tied with chelsea at 1st place. that would be an awesome head to head race till the end...
