I've been waiting for FM23 to try and take a shot at replicating Arteta. Of course, huge Arsenal fan and have been watching, reading and learning the team's setup.
Anyway, I've only played one game on full match so I wouldn't say my plan is set. However, I've seen enough to make decisions on the player roles. Ultimately, I feel that is the key part on replicating the style of football they play besides the usual high press, trigger press opposition's backline with high defensive line, tight mark hard tackle the middle and show their fullbacks inside.
I saw BTN's video on it although I agree in some parts (like the above) I haven't seen the IW and IF with stay wider holding the width even on Very Wide team setting. In fact, most of what has been said here is true about Mez occupying the same space as the IF. So, I came up with the roles below.
SK (d) - Rambo
WB (s) - White/Tomi/Cedric
DC (d) - Saliba
BPD (d) - Gabby
IWB (s) - Zinchenko
DM (s) - Thomas
MCR (a) - Odegaard
BBM (s) - Xhaka
IW (a) - Saka
IF (s) - Martinelli
F9 (s) - Jesus
In my mind, I'm trying to have the fluid movements and rotations in the left side of the pitch before the switch over to Saka with his 1v1 and White supporting, then everyone arrives in late in the box. Our fullbacks with Xhaka/Odegaard tight mark and hard tackle as we force them inside. I decided an MC (a) with Moves Into Channels, Dribble More and Roam From Position over the usual Mez (a) as they are little too wide. Martin only goes on the outside if White and Saka inverts. As only Saka is inverting while White provides the width near the box, makes much more sense for Odegaard not to go wide too often and combine. Still need to see more games on this though.
Jesus on F9 is useful as he will overload the middle but I added Roam From Position trying to replicate the movements he has with Martinelli whose also on Roam From Position. Xhaka on BBM only feels natural attribute-wise but I've yet to see the difference between that and the Mez (s).
To be perfectly honest, with the match engine, I think we can only go as far as replicating one side of Arteta's style of play. I've been toying with the idea of their 4231 into a 442 when defending while also having the 235 positional play structure but I think it's difficult. Also the fact that Arteta always have Saka/Martinelli man marking/pressing the opposition's centerbacks and White/Zinchenko push up on their fullbacks while Odegaard marks their pivot with Thomas/Arteta stepping up in a flat two man marking.
