wrong 4-3-3 formation

[BSH]

hi I've been playing football manager games since 1995 on the PC and now I don't play games anymore on the PC, because I have consoles...but wanted to tryu this with facebook.

I would like to know why I can't make a 4-3-3 formation like this:

LW--------ST--------RW
----------AMC----------
-------MC-----MC-------
DL-----DC-----DC-----DR
-----------GK-----------

OR:

LW--------ST--------RW
-------MC-----MC------
----------DMC----------
DL-----DC-----DC-----DR
-----------GK-----------

These are my 2 favorite formation and I can't use them in Top Eleven.
With the two forward wingers (LW and RW) wide against the sideline and the 3 midfielders all play central.

I hate the 4-3-3 in top Eleven with the 3 central strikers!! no team IRL playes like this!!


Also a question about the red arrows...
When I place a red arrow on my DMC, then when in ball possession that DMC will move up one square and becoming a MC.
But how does this translate to the AML and AMR with red arrows? because in front of those positions...there is no square availiable.

At the moment I play this formation:

-----------ST-----------
AML----------------AMR
-------MC-----MC------
----------DMC----------
DL-----DC-----DC-----DR
-----------GK-----------

But I want those AML and AMR to be LW and RW
