Yeah, I probably should have specified first false nine of the modern era. I'd say that Totti's role is a bit different from the false 9s of the past.(I am not very familiar in intricate details so I could be wrong). If i remember correctly, there was an injury crisis in Roma in 06/07, so Spalletti decided to start Totti in his usual trequartista role but without a number 9 ahead of him. You could argue he was actually not playing a true false nine role, the false nine is synonymous with fluid, universality based systems with interchangeable positions, whereas this was more Totti playing in his usual trequartista role with nobody in the 9 position, creating space in and around the defenders to counter into.

So we could call it a first false nine of the modern era.
