Juventus insist that Claudio Marchisio is not for sale and the player himself says he is happy at the club.
The midfielder, a product of Juve's youth academy, was linked with a move to Premier League champions Manchester United last month.
Big-spending Monaco, who have already splashed the cash on the likes of Joao Moutinho, James Rodriquez and Radamel Falcao this summer, are also rumoured to be keen on the 27-year-old.
Juve, though, are not entertaining any thoughts of letting the Italy international leave this summer.
"Our goal is not to sell but to strengthen the team," general manager Giuseppe Marotta told Sky Italia. "Marchisio has Juventus DNA and the player's will is influential."
When asked about his future Marchisio was equally emphatic, telling Tuttosport: "I want to stay at Juventus.
"I would like to continue battling for and winning with the club in which I grew up in."
