RealGM

First off, let's keep it within the realms of possibility in here.

Atletico Madrid
Barcelona (assuming their transfer ban gets overturned)
Real Madrid
Bayern Munich
Borussia Dortmund
Liverpool
Chelsea
Manchester City
PSG
Monaco
Juventus

I would go with these:

Atletico: Hiroshi Kiyotake
Barca: Naldo
Real: Holger Badstuber
Bayern: Granit Xhaka
Borussia: Mario Balotelli
Liverpool: Saphir Taïder
Chelsea: Adrian Ramos
Manchester City: Alan Dzagoev
PSG: Park Joo-ho
Monaco: Radja Nainggolan
Juventus: Adam Lallana

Costas would look so damn sexy replacing Lewy.
