You need to look at the germans, not the spanish or english clubs. By the way, both Stuttgart and bayern munich are likely to end up 3rd in the CL group stage which means they'll both play in the Europa league.
Adding Hamburg (one step close to the next round), Werder Bremen (allready qualified to the next round) and Hertha Berlin who are second and have a good chance making it to the next round.
Thats 5 german clubs > 2 possible italian clubs
