Roma president James Pallotta says a rejection of his club's new stadium plans by the city council would have "catastrophic" consequences for the Giallorossi.
The Eternal City club are bidding to build a new arena in a currently disused area of the city, but initial reservations against the idea have escalated during a series of council meetings to discuss the project.
A definite answer on the part of the council over planning permission is due on Friday, and Pallotta has expressed his hope that the green light will be given, otherwise he says the future would be particularly bleak.
"We expect a massively positive result from the meeting on Friday," Pallotta said on his club's website. "The alternative would be catastrophic for the future of AS Roma, Italian football, the city of Rome, and quite frankly for future business in Italy."
Roma have already invested upward of €60 million in the stadium project, which is still stuck in its planning stage, despite initial hopes they would be able to open the gates to Serie A football in 2018.
Planning permission and bureaucracy has left many of Italy's stadia unaltered since prior to when the country staged the World Cup back in 1990, while most clubs continue to rent their grounds from the city councils and are therefore unable to or unwilling to fund improvements.
Roma and Lazio are currently tenants at the Stadio Olimpico, which is owned by the Italian Olympic Committee (CONI).
Juventus and Udinese are the only Italian clubs to have succeeded in rebuilding their stadiums in recent years. Since the Bianconeri moved into their new Juventus Stadium home in 2011, they have won Serie A each season.
