I've played 4-3-1-2 mostly and have just started playing 4-2-3-1 but what I have noticed for both is my players don't attack in numbers.
I usually go attacking straight away in game but regularly have my CAM Gomez ending up behind my CDM Matuidi whether I'm attacking or defending. I even have my CAMs set to stay forward but that doesn't seem to make a difference. So now I have no chance of counter attacking as I usually have Higuaín at around the half way line who has to hold the ball up for ages in which time their defenders get back into position.
I even went ultra attacking in my last game and that seemed to make no difference.
Is there any other way of telling players to stay forward than player instruction?
