Fix defensive positioning

[wise lava]

easily the most frustrating thing about this game at the moment is the defensive positioning, particularly the positioning of the back four where they just wander off wherever to try and tackle the attacker, leaving loads of space elsewhere for an easy goal. Also the positioning of the midfield isn’t great either where often I find my midfielders standing around doing absolutely nothing and letting the ai just glide through and leaving the defence to deal with it. Please fix this
