Matthijs de Ligt will make his move to Juventus.
The Ajax captain arrived in Turin on Tuesday night before moving to the Italian championship for £ 67.5m.
De Ligt had turned out to be the hottest house in world football this summer after leading Ajax to the semi-finals of the Champions League.
Manchester United, Liverpool and PSG were all inclined to be interested in the Dutch defender, but it was Barcelona in pole position.
However, the Spanish champions failed to agree and Juventus rushed to Turin with De Ligt before posting a message to Juventus fans on social media.
He is expected to undergo a medical examination on Wednesday before switching to the Italian champion.
Earlier this week, there were reports that Barcelona had tried to abuse the deal at the eleventh hour.
Mundo Deportivo claimed that Barca had made a late trick to qualify for De Ligt. President Josep Maria Bartomeu sought personal talks.
Bartomeu was planning a trip to Amsterdam and despite the agreement with Juventus De Ligt was open to meet him.
His agent Mino Raiola intervened and spoke with the Barca boss. He advised him to only discuss if the La Liga giants could meet the conditions of Juve – about 9 million pounds per season.
It is alleged that Bartomeu has decided to end his interest in De Ligt in order to complete his move this week.
However, it has already been reported that Raiola De Ligt has advised that he can afford to wait a few more years before switching to a European powerhouse.
