The reports have sparked rumours over which players could join boss Rafa Benitez if he moves to Italy and Kuyt has seen his name linked with the Serie A club.
However the forward, who Benitez bought for £9million from Feyenoord in summer 2006, is happy at Anfield, according to Jansen.
"I know nothing of Juventus' interest," he told Calciomercato.it.
"No-one has contacted us at the moment. He is now happy at Liverpool where he has two more years of his contract left."
"The relationship with Benitez is excellent," he added.
"If Dirk could follow Rafa when he becomes the next coach of Juventus? I don't know. I cannot answer these questions now."
