Or maybe "Boy, do I have a lot of amazing fullbacks and wingback!"?
Yeah, me neither.
However, if any of you like the idea or just enjoy somewhat unorthodox formations, boy, do I have a tactic for you!
Created and tested on 20.4.1, personal testing results below:
Liverpool (finished 1st, won CL, got knocked out of the Carabao Cup by the almighty West Brom Albion):
~2,53 points per game
~2,61 goals scored per game
~0,42 goals conceded per game
Milan (finished 2nd because of losing the direct duel, won Coppa Italia):
~2,18 points per game
~1,95 goals scored per game
~0,61 goals conceded per game
Celta Vigo (finished 2nd):
~2,32 points per game
~2,37 goals scored per game
~1,03 goals conceded per game
As you can see, having 6 defenders does not prevent you from scoring a lot of goals.
The tactic was tested WITHOUT specific set-piece instructions or training in order to give you the purest possible results. If you use proper set-piece routines, you will most likely perform even better.
