First season with Man City I went unbeaten and won all major trophies (PL, FA, EFL and CL)
The tactic itself uses a CM and Mezzala in midfield and 2 inverted wingers. The two fullbacks are instructed to keep the pitch small and the inverted wingers to keep wide to create room to pass the ball around and to give everyone multiple choices to give the ball.
I don't use OI to prevent my players being drawn out of position. Training is left to AM with the occasional tweak (review game of heavier load whenever I think it's possible).
Set pieces I used Knap's beowulf as blueprint.
