Juventus coach Massimiliano Allegri is adamant Daniele Rugani is not for sale.
The young Italy U21 defender is a top target for Arsenal and Manchester United.
However, Allegri told La Domenica Sportiva: "He will remain at Juventus for ten years, because he is our future.
"Right now he is faced with three defenders of the Italian national team and it is difficult to give him space, but his time will come.
"I love how he is training, he is growing a lot."
