Okay i can play 3-1-5-1 but with which tactic? this is not two much in the middle, i have a strong second ST and a strong AMC

And i have now some questions for the formation,too.

So i have some ideas for a formation:

1.)

3-1-4-1-1

GK (down)
DC (down), DC (down), DC (down)
DMC (normal)
MR (UP) MC, MC, ML (UP)
AMC (UP)
ST (UP)

tactic: ???

2.)

3-1-5-1

GK (down)
DC (down), DC (down), DC (down)
DMC (normal)
MR (UP) MC, MC (UP), MC, ML (UP)
ST (UP)

tactic: ???

3.)

3-1-4-1-2

GK (down)
DC (down), DC (down), DC (down)
DMC (normal)
MR (UP), MC, MC, ML (UP)
AMC (UP)
ST (UP)

tactic: ???

4.)

i must buy a DL

and so than i can play with 4 defense player but this is to much i think.

is it better to play with 3 or 4 defense player at the end?
