That's obvious I'd say. Sarri requires his wingers to run a lot, in defense too. In his system, only the CF can be lazy while defending.
CR7 as CF has other significant implications:
- there's no place for Dybala (too expensive to stay on the bench)
- Kean most likely to be the backup CF since Higuain is too expensive to keep on the bench, while Mnadzukic is not Sarri's type of forward.
- we'll need at least one more winger, that is if Cuadrado stays (if he goes we'll need two wingers as we'd have only Berna and DC)
