Agent isnt registered with UEFA or the FA, but is registered with FIFA..
They need to be registered with both UEFA and the FA to negotiate with transfers in the PL... or they should be at least. Seems thats gone out the window now.
What you've got to remember is the transfer went through in 2009. It is ridiculous that this came up IMO. It should have been brought up a long time ago, not now. Once again the governing bodies of football show their ineptitude.
