Well that's a chance the club appears willing to take and quite rightly in my opinion. The bottom line is, there is a professional code of conduct that all players have to abide by and Rooney is no different. If he isn't pulling his weight there are punitive measures that can be taken against him, a position we all hope will not materialize. I also believe that Rooney is not stupid enough to rock the boat that far, it will not bode too well for his future employment prospects elsewhere. Let's also not forget, the world cup is next year and by all counts Rooney will be aiming to put himself with every bit of a shout to lead the line for England, should they go to Brazil.
It's exactly for the above that the club has behaved the way it has in this sorry saga. The player has been reported be be disillusioned, apparently seeking a move from the club AND the club having evaluated all options available to it, has seen it FIT to NOT grant him his wish(es). This is a case of the club seeing more collective benefit of having Rooney around than selling him, a simple and clear case of the needs of the club being put far and above those of an individual !
