Paratici's role is same as before Marotta left, sporting director. The way I see it, Paratici was always in charge of player trading, excluding transfer budget, and required approval of someone or more from BoD before a transfer went through- Marotta, Nedved, Agnelli etc. Marotta as CEO was in charge of day-to-day running the club, standing in for the President until now. Either the president's/chairman of BoD or the vice-chairman's role has increased in absence of Marotta.
