"I have very good contact with Juve and my agent is in Turin to have negotiations," Sissoko told Sky Sports News.
"Yes in the next two days I think the transfer is open.
"It is a very big club and I like this team. For the future they can do very good things, that is why I want to join Juventus."
Sissoko also said he did not have a problem with Liverpool manager Rafael Benitez and was only leaving Anfield because he was frustrated with his lack of first-team action.
"I think it was not a very big problem [at Liverpool]," added Sissoko.
"I am 23 years old, I am still young so I want to play a lot of games and that is why I leave Liverpool."
