Matthijs De Ligt has been warned against a summer switch to Old Trafford by Manchester United legend Jaap Stam.
The Dutch defender was strongly linked with the Red Devils last year before joining Serie A giants Juventus instead.
However, rumours of a move to United have surfaced again after struggling for form in Italy where he has so far been limited to just 15 league starts.
However, Stam, who won three Premier League titles during his time at Old Trafford, has told his compatriot to stay at Juve and fight for his spot.
He told TuttoJuve.com: "I think it’s fundamental that De Ligt stays at Juve for many years, because it’s the only way to improve, by dealing with the best, learning to live with pressure in important Champions League and Serie A games.
"He was criticised a little but had to understand how to adapt to a different style of football. He’s still young and Matthijs is at a big club with far more pressure than he was accustomed to.
"The standard of opponent he is facing in Italy is also far higher than in the Netherlands.
"Juventus invested a large sum to sign him, some way would say too much, but in my view he has done well so far.
"The experience has made him believe in himself more. He just needs to learn Italian so he can communicate with his teammates."
Stam has urged De Ligt to learn off experienced defenders Giorgio Chiellini and Leonardo Bonucci, adding: "They are top level defenders, real winners accustomed to the biggest games.
"They are the best centre-backs in Italy and they can teach him so much on the art of defending."
