^^^Wow if Robbie goes there, Sunderland may be in the 10-12 positions and Sheffield will probably fall down next year.
As for West Ham, I think that the FA can't do anything right now. They didn't do anything to stop the transfer at the time. You can't turn back time... I think that atm the most appropriate thing would be a pretty big financial fine, as they didn't react in time and it's been a few months since then.
