This is just going off Transfermarkt, which is pretty reliable but not 100% accurate. For instance, Rico often plays a hybrid role that you can only really judge with the eye. He might technically appear in a "midfield two" on the teamsheet but will spend most of the game alongside the CBs. Still, just going off raw data.
Of those 67 games he's played, he's apparently started 49 of them.
Of those 49 games he's started, he's been a defender in 27 of them.
So that means he's started 22 games as a midfielder.
Of the three goals he's scored in a City shirt, two of them have come when playing in midfield (both vs Crystal Palace) while one of them came while playing in defence (vs Sevilla).
Of the eight assists he's provided, three have come from defence and five have come from midfield.
So when starting in defence his record is 27 appearances, 1 goal, 3 assists. And starting in midfield his record is 22 appearances, 2 goals, 5 assists.
If a teenager finished a season with 44 games, 4 goals, and 10 assists from central midfield you'd expect a bit of improvement but you could really see the potential imo.
