VfB Stuttgart defender Antonio Rudiger is emerging as one of the hottest transfer properties on the continent.
Juventus are the last European giant to be linked with the young German.
His agent, Benjamin Ippoliti of Fair-Sport, revealed to Calciomercato.com: "In the summer we received many requests from Monaco, Porto, West Ham United - and not only them.
"But now he must focus only on Stuttgart and respect his contract: here he is happy and in recent years has improved a lot."
Asked about the Juve rumours, Ippoliti continued: "Juventus? There has never contact, but I cannot exclude that they've sent scouts to follow him - or there's been contact with VfB Stuttgart.
"I don't think in January anything will happen: the table position is good and Rudiger is considered to be a major player. "
Indeed, in August, Stuttgart rejected €15 million from AS Monaco for Rudiger, who has since confirmed the interest of Manchester United.
"I know about Manchester's interested, I've noticed it," he told BILD.
"This is of course is a top international address. And they play in the League which I dream of."
