The Bianconeri director general explained that the Verona player's agent is poised to arrive in Italy to finalise personal terms on behalf of the 27-year-old
The Gialloblu only acquired outright ownership of the versatile midfielder earlier this month but have now agreed to sell the 27-year-old to the Serie A champions.
"Romulo? Between today and tomorrow will be a Juventus player," Bianconeri director general Marotta told reporters on Thursday.
"His agent will be here tomorrow in Turin to close the deal."
Indeed, the Italy international's representative, Alex Firminio, is not expecting any last-minute hitches.
"It is virtually a done deal with Juventus," Romulo's agent told Calcio News. "We are delighted and want to thank everyone at Verona for believing in him.
"[On Friday] I will arrive in Italy and we will sign [the contract]. I’ve spoken to Romulo and he is really happy to have been given an opportunity like this at Juve."
