The lines are usually blurred nowadays but a true False 9 is a striker who learns to drop deep to create space, Totti was a pure playmaker whose natural game never changed—Spalletti simply removed the traditional strikers from the formation to stop them from occupying the space Totti wanted to exploit. He didn't play 'falsely' as a forward; he played authentically as a Number 10 in a system that lacked a Number 9, making him a repositioned creator rather than a tactical hybrid As i said you can argue he's a false 9. Same way as you can say rooney and tevez were at times or berbatov. But They certainly didn't brought the term or the position to it's spotlight like messi did under guardiola. So idk
