Teenage Netherlands centre-back Matthijs de Ligt has agreed to join Serie A champions Juventus from Ajax, according to reports.
Sky Italy report that Juventus will pay STG 62 million ($A114 million) for the 19-year-old Ajax captain.
De Ligt was one of the key players in the Dutch side's thrilling run to the UEFA Champions League semi-finals.
He will become new Juventus head coach Maurizio Sarri's first signing after the Italian's appointment last week as Massimiliano Allegri's successor.
De Ligt said earlier this month that he had been asked about a move to Juventus by Cristiano Ronaldo after Portugal beat the Netherlands 1-0 in the UEFA Nations League final.
"I didn't understand him at first. I was a little shocked, so I laughed. But I didn't say anything," de Ligt had told the Netherlands' NOS television.
"So soon after the game, you are not at all concerned with it. You are disappointed that you have lost and that is the only thing you are thinking about."
Spanish media reports had said the highly rated player was expected to join Barcelona and link up with Ajax's Frenkie de Jong, 22. De Jong is set to move to Spain next month.
De Ligt broke into the Ajax first team in 2016, aged 17, becoming a regular starter the following season and soon became the most-coveted defender in Europe thanks to his strength, anticipation and ability on the ball.
He played 90 minutes in 17 of 18 matches and scored three times in Ajax's Champions League campaign, which culminated in an agonising semi-final defeat to Tottenham Hotspur on away goals.
