[Potemy]

Thanks but i play 442,

Would i win a lot more possesion if i move those 2dmc to mc instead, and how mutch will this effect my defence?
Hope ya understand what my problem is,
Thanks up front

How much possession are you getting with this formation? The last time I left the middle row empty, I had 20% possession, it seemed to be illegal somehow, I started getting normal possession when I moved a DMC to MC.
