The phrase rats deserting a sinking ship springs to mind! Without an in-form Rooney United are shit and he's understandably had enough it seems.
With the Glazers Fergie will be lucky to get £10m to replace him, and that's if they get a good price for him - he could buy himself out of his contract for £5m in the summer if he doesn't go in January, so that'll hit his value. Only City would pay a decent amount of money now.
