The defender, 25, was widely expected to complete his move to the Serie A champions this week, but Petrachi has stressed there is no agreement yet between both clubs over a transfer fee and is ready to listen to other interested teams.
"Juventus have yet to get back to me to close the deal," Petrachi told Sky Sport Italia. "It's a logical consequence that other teams that were already interested in signing Angelo before Juventus came up have returned for him.
"I don't have any preference as to where he goes if he leaves. I can only say that the teams that have returned are back in the race. Those who have contacted us have made serious offers."
Ogbonna, who has a contract with Torino until June 2016, has also been linked with clubs such as Manchester United and Napoli.'
