Massimiliano Allegri has reminded Matthijs de Ligt's critics that even Giorgio Chiellini had his struggles as a young player and is convinced the Dutchman has a long future ahead of him at Juventus despite Mino Raiola encouraging speculation.
De Ligt joined Juve on the back of Ajax's unlikely journey to the 2018-19 Champions League semi-finals, in which he played a vital role as he helped build moves from the back with his passing abilities but also proving a dominant physical presence despite his tender age.
His 0.45 headed shots on target every 90 minutes was the most of all defenders in the competition to play at least 270 minutes that season, while only four of them bettered his 4.2 aerial wins per game.
While De Ligt has not made quite the same use of his physicality at Juve, those strengths could lend themselves to a future in the Premier League, where he is thought to be admired by numerous clubs, with his agent Raiola suggesting on Saturday that the Dutchman may not see out the rest of his contract, which runs to 2024, at Juve.
Raiola's comments came after seeing De Ligt dropped for last week's 2-1 defeat at Napoli and playing in only one of the Netherlands' three recent World Cup qualifiers, with the centre-back yet to truly convince since signing two years ago.
The spotlight is very much on Juve's defence ahead of Sunday's clash with Milan, as they have conceded in each of their previous 17 league games, the third-longest run in club history and the worst currently across Europe's top five leagues.
But Allegri appears to retain belief in De Ligt, backing him for a long future at Juve.
"I've already said it before; De Ligt is 22 years old, he's very good, but when you arrive at Juve with an enthusiasm that overwhelms you, it's normal to lose some clarity," the Juventus head coach told reporters when asked about Raiola's comments.
"When he was signed, someone described him as a future Ballon d'Or winner, but it requires tranquillity. He was a 20-year-old boy who arrived at Juventus, a shirt that weighs heavy.
"Chiellini at 20 was like De Ligt, or maybe worse. Then at 28 he became a serious player.
"There is a path for everyone, players and coaches. De Ligt is still a young, good player, who can stay at Juve for many years, regardless of whether he plays one more or one less game."
