And what about tactics for my match against 4-5-1? Should I press whole pitch? mixed passing, short, zonal? I never played with 3 defenders before.
And what about the arrows, how should I put them in 3-5-2?
Also if a player is outside their normal position how much would this affects this the game? Because I could have a team 3-5-2 on their favorite positions but than my team would be of slightly less quality. Is this better than butting players on wrong positions?

Thx for the help so far
