I'm not sure where you all get these superb player profiles from, but I'm guessing you just hunt around the internet, particularly Wikipedia.org

If you find good material to use for a player profile but can't create one yourself suitable for posting here, please post a link in this thread to your source.

For example, I've found a nice short one about Manolo here:

This is a very good source of information:

Proper articles, not fact sheets like some of the Wiki entries tend to be.
