Milos Krasic's representative claims his client has set his heart on making a move to Juventus.
Reports had suggested that Inter Milan had taken the lead in the race to land the Serbia playmaker, while Manchester United and Manchester City were still chasing hard.
However, it now appears that Inter are not in the frame and United are exploring other options.
That has left Juve in pole position, as Krasic has expressed a desire to move to Italy.
It is expected to be only a matter of time before he seals a switch away from current employers CSKA Moscow, but where he will end up remains a mystery.
His representative Marko Naletilic claims an agreement with Juventus would be preferable, but he admits that the Serie A giants need to work quickly if they are to reach an agreement.
"The move to Juventus is still a possibility, but the situation is complicated." Naletilic told calciomercato.it.
"I am moderately optimistic, but we will have to see.
"CSKA Moscow have taken four or five days waiting for an offer from Manchester City.
"Inter Milan? Actually, Juventus and Manchester City are the only clubs involved at the moment.
"The problem for CSKA is that Krasic wants to join Juventus and doesn't want to discuss other destinations.
"When will there be news? I cannot say, but Juventus cannot afford to wait too long."
