Unicredit lawyer Roberto Cappelli has been appointed president of Roma following delays in the takeover by Boston executive Thomas DiBenedetto.
A group of American investors led by DiBenedetto signed a deal in April to take over the Serie A club, but the change has not been approved by Roma's board of directors yet.
Roma says in a statement that it has also hired former Lecce chief executive Claudio Fenucci as its new CEO, and given the new executive board powers to run the club - essentially ending the Sensi family's 18-year reign at the club.
Lately, the club has been without an executive authorized to sign deals for new players, stalling the team's transfer market deals. New coach Luis Enrique has yet to be introduced.
DiBenedetto is still hoping to become president by the end of the month.
