Bundesliga are tough with their license. Besides, FIFA doesn't even have the license for several teams in leagues where they claim to. PES will never be about having a full license, in fact for many the edit feature is 50% of the game, and the free league they leave in lets you add the Bundesliga if you want (patch or download option file), or you can add any teams you want.
I must admit, I have made a few teams before, including a Juventus Legends one.
