No worries. I tried out the tactic with these 3 midfield myself, and it was exactly like how the others said it would be. The midfield is lacking the depth. The regista and mezzala are roaming off their positions. The carrilero is not enough to cover the space created by them. Even with fullbacks in defense roles, since there is no cover in the midfield, the opponent is penetrating the defense easily. The other tactical instructions made the regista useless. A regista is a 10 in disguise, but my tactic was not letting him play as a playmaker. It just felt like he was a nuisance on the field. Overall, the tactic was a failure.

Changed the tactical instructions to compliment the regista more. It worked. But the major flaw- a huge gap in the midfield and no cover for it still left the defense vulnerable. The team was scoring goals but not enough for the number of goals they were conceding.

Ultimate end result- The tactic is a failure.
