I remember reading an article before saying that if the FA were to investigate it again, then Aldridge would be called in to answer questions - he wasn't interviewed previously.
Now bearing in mind that the FA wouldn't investigate if they weren't expecting anything to come up, chances are something will come of this. Paul Aldridge was involved in the affair, and now sorts out the transfers of players with Gary Cook.
If he gets found to have behaved improperly, I can bet the the FA or the police will be just checking over the Robinho and Bridge transfers.....doubt them two deals with have anything dodgy, but as a matter of process, they should do.
