Lurker,
Honestly, Rooney's parents will have barely paid anything for his development. Think about it, Everton have him, and realize how much potential he has, and therefore pay for everything, because if they don't, Rooney's parents will just move him to another club. On the Freddy note, as soon as he was picked to go into residency in Bradenton, his parents no longer had to pay for anything, so really, he has been a relatively inexpensive child for them. Sharapova's parents will definitely have paid a lot more then Rooneys for the success they have enjoyed.
