Madrid played this last year but it failed, it requires a huge amount of tactical understanding from the players. it is how Madrid fell into the 4-1-2-1-2 diamond.
Madrid played it with:
Navas;
Varane, Casemiro, Ramos;
Isco, Kroos, Modric ;
Ronaldo;
Marcelo, Benzema, Bale
it is worth taking into account this formation is ONLY for attacking phases. The defensive set up is a 4-4-2:
Navas;
Marcelo, Varane, casemiro, Ramos;
Isco, Kroos, Modric , Bale
Ronaldo, Benzema
It required too much running for the wide players, so Zidane decided on a diamon midfield during attack and flat 4-4-2 in defense, which they still play and dominate games with (E.g Barca recently)
