I tried the 433 you’ve set up and the movement of the midfield three was really interesting. The carrilero and RPM switched places a lot and the carrilero would a lot of times be the deepest when the RPM surges forward. I tried using a DLP thinking it would be more secure, instead him holding position made everything worse as he wasn’t supporting the right flank enough, and the carrilero was too static. I never would’ve thought to use an RPM there.
The IF-s does tend to get isolated sometimes if the ball gets to him early so I kinda get why you’d use an SS. But with an IF would you use anything besides an AP-WB combo to support it?
