1. Always advise on all kinds of tactics and forms of putting players (4-4-2, 4-3-3) that fit specific games, but when I do I don't necessarily notice improvement in all my players squads, and other forms that they don't know and so Balanced I notice a marked improvement, for example, in the defensive squad (in percentage against the opponent), that's what I don't understand. 2. How can it be that when I take down players from the defense, then my attack gets stronger and not when I put a thickened defense squad of 5 for example. Thanks.
