Joorabchian, who is acting as an intermediary in the negotiations between the two clubs, has revealed that the 32-year-old Brazilian could join the Premier League outfit this month.
"Yes, Julio Cesar's transfer to Queens Park Rangers is very probable," he told Tuttomercatoweb.com.
"We are working and talking. Next week the deal could go through. I have not spoken with Inter, Julio has. Let's see what happens.
"His arrival at QPR is absolutely possible. I think we'll do it."
Julio Cesar's place in Inter's starting lineup for the 2012-13 season is under doubt following the Italian club's acquisition of Samir Handanovic from Udinese this summer.
