It’s more the big money move to Italy and then going back the Brazil for a fraction not even 6 months later. And the wording (which might just be bad editing) suggesting fiorentina might not have benefited from him going back to Brazil. On reflection that is surely bad writingI assume he is part owned by multiple parties then? Pretty common in South America
But it screams “agent bung” to me like with Bebe to Man United
