If he gets de Jong, our initial build up phase will likely be close to the CL semi-final side, which would make 4231 my go to, probably with 2 DMs. I'd lean towards Regista for de Jong as they seem to collect the ball deeper and sit a little more behind the play. Wont exactly give you a back 3, but I'd personally rather recreate the on-ball play we saw from de Jong and I don't think any defend duty role will give him the freedom to dribble and roam around. Schone probably goes in as a DM(s) and van de Beek could be in the MF or AM strata, maybe as a CM(a) or an AM(s).
If we don't get a de Jong, maybe he gets a Daley Blind instead - a fullback who can step into midfield. In that instance I'd go with an IWB, and a 433 based off the season gone would look more likely. The duty depends how much you want a back 3 or if you prefer to replicate the creative aspect of the role. The midfield there is probably something like DM(d/s) with Gravenberch a BBM/RPM and Berghuis as a Mezalla - close to what you've got actually.
As to the forward 3, a pair of inverted wingers is likely, but Ronaldo's role is anyone's guess. He did loads of roaming around last season, but maybe under Ten Hag he gets him more up against defenders, or maybe he has him float around the pitch. I'd probably start with CF(a), but it could just as easily be TF(a) or a poacher - Ten Hag has used all types in his career.
If you're looking to create an overload for Ronaldo to exploit btw, I'm not sure trequartista is the way to go, because it will probably lead to him engaging with your right side too much. I've had a lot of joy with a poacher in a 433, as it very much exploits the central space when you get a flank overload. The tradeoff (for me anyway) is that you're unlikely to see the team dominating possession game to game if your only striker is always looking to break the defensive line, but it leads to a lot of goals. Team instructions can help balance that if it bothers you though.
