Missing players

I noticed from other FM15 stories that there are players which don't exist in mine FM15, such like Luka from Maribor, Rafael Toli, Embolo from Basel, Darmian from Torino...

Do you have idea why?

I just got FM15 this year, sorry for being such a noob.

If you want all these players included in your game make sure you load the databases for their respective leagues.
