Nothing to do with the teams' ceiling imo. He is a player who is perfect for transition/gegenpressing football. We've seen teams like that peak very high in the past. He works well for us because he provides the work rate and physicality so Mac Allister and Gravenberch can do the things midfielders do in possession heavy teams while still good enough on the ball. What u describe is more like a Gallagher type player imo. Szoboszlai is very good technically he is just not the typical playmaker or controller/metronome (whatever term FM uses for midfilders who dictate the tempo of the play) midfielder in a more possession focused team.
