I thought a cf is a false nine. I don’t understand why the terms are used as meaning the same thing, since they are not.
Someone correct me if I'm wrong but the way I see it:
- Centre Forward: Basically a striker, someone whose main role is scoring goals. Type (specialty) differs from those that dribble (Henry), pure finishers (Van Nistelrooy/Solksjaer), link up play (Martial), speed/finish combo (Rashford, Mane, Salah). Can do a job on the wing (if they dribble like Henry or have speed like Rashford, Mane, Salah) but 90% of them would be ineffective there (imagine Van Nistelrooy, Ibrahimovic, Lukaku as wingers).
- Support Striker: The Rooney position. Plays as a "striker" just behind the other striker and links up play between midfield, wings, and the other striker. Main job is also scoring goals but has extra role in assisting with link up
whenever possible. Should have good passing/crossing range, and mobility.
- False 9: Attacking midfielder. Primary role is to link up play and open passing lanes between himself, midfield, and wings. Very good for a possession based team where most of the players' strengths are link up and quick passing to open up space for each other. Usually a CAM with great passing and very mobile. Can play on the wing/center midfield and be effective most of the time. Not necessary to be a clinical finisher as the goal scoring burden should be spread out between all 6 players (midfield+wingers+false 9) due to increased openings via quick passing.
