Elias Figueroa, a lot should be done to be Ronaldinhos idol.(I know he is not close to being like Pele though, but maybe one of the bests in his position)

Rummenigue was not a pure number 9 forward, but more like a 9,5 and yet he scored many goals. See his profile

As a classic forward maybe Van Basten was number one.

I followed most of Rummenigge's career and while he was a very good player he never really impressed me like - say - Lothar Matthäus (different position, I know, but to me Lothar was always a better player than Kalle).

here's another question, who do you think has "potential" to become that good?

Of all current players: Messi, Kaká.

"That good" is a difficult question. I know this guy has the potential to become one of the best central defenders in the world, but I don't know if "of history"

Other than him...let me think a bit. Messi of course has the potential to enter history, but we'll see if he realizes all he promises

ill keep an eye out for that guy on Football Manager, if he is that good, ill buy him!

id say Messi and Ronaldo both have the potential, sure Ronaldo is an arrogant prick at times, but if you could play him at his best on the right of your midfield, would you complain? 

Haha, but FM has the tendency of underestimating Argentinian youngsters (and the FM info is from 2008, when the kid hadn't "exploded"). But, in FM2010 he'll be a star, since he was one of the best players last season

oic, cool, even on FM09, i see his stats now, there not bad considering, and im gonna see what my scouts think of him.

Steven Gerrard anyone?
