I do like to have 3 CMs on the pitch at the same time, somehow this makes the team more compact/less exposed and I think that's something that we'll need vs Lazio a lot.
Szczęsny
Cuadrado - Demiral - Bonucci - Danilo
McKennie - Bentancur - Rabiot
Kulu - Morata - CR7
I couldn't care less about the formation, so place those players in whichever you like more.
Just don't be that dumb to lead the possession game, to be caught exposed on counters, thank you.
