This is a really great thread with lots of debate on the different ways/variations of recreating Arteta's tactics. I have just started thinking/playing around with my interpretation Here is what I have done:
I went with 4-2-3-1 (4-1-1-3-1)
v1
GK: Sk (s)
RB: FB (s) CB: BPD (c) CB: BPD (d) LB: IWB (s)
DM: DM (d)
CM: BBM (S)
RW: W (A). CAM: T (A). LW: IW (s)
ST: DLF (A)
RB: sit narrow, hold position, run wide, dribble more
DM: tackle harder
BBM: stay wider, get further forward, cross more
IW: Stay wider, get further forward
W: roam from position, mark DCL (to create pressing front 2)
v2
GK: Sk (s)
RB: FB (s) CB: BPD (c) CB: BPD (d) LB: WB (s)
DM: DM (d)
CM: BBM (S)
RW: W (A). CAM: T (A). LW: IW (s)
ST: DLF (A)
RB: sit narrow, hold position, run wide, dribble more
LB: stay wider, dribble more (for Tierney variation)
DM: tackle harder
BBM: stay wider, get further forward, cross more
IW: Sit Narrower, get further forward
W: roam from position, mark DCL (to create pressing front 2)
TIs for both v1 and v2 would probably be:
Shorter passing, play out from D, low crosses, work ball into box, focus play L and R, Fairly narrow
take short kicks, counter press
Higher def line, High press, more often
I really like Ødegaard as a T because he creates overloads either side and links nicely with Saka as he does in real life.
I think Saka as a W (a) on the right is as close as you can get.
With Xhaka being limited as a CM on fm23 it's a shame he isn't perfect for BBM or an SV as that is his real role.
You could also easily do a 4-3-3 by shifting Ø into the midfield 3 as a AP (a) and Xhaka as a Mez (s), the variations are endless.
