Most teams either plays with 2 CMs or 3 where atleast one of them is a CAM like Isco, Kroos, Muller.. I haven't seen many teams fielding 3 average CMs who are primarily defensive. And especially not leaving players like Costa, Berna, Dybala or Cuads on the bench.
Isco at RMA played CAM in a 4-4-2 diamond which is essentially a 4-1-2-1-2:
- - - - - - Casemiro- - - - - -
Modric - - - - - - - - - Kroos
- - - - - - - - - Isco - - - - - - - -
- - Benzema - -Ronaldo - -
That's the team and shape Madrid used against us both in 2017 & 2018.
