Bayern Munich have signed the Netherlands defender Matthijs de Ligt from Juventus on a five-year contract in a deal worth €80m [£67.8m].
The fee was equal to the transfer record of the German club.
De Ligt joined the Bianconeri on a five-year contract in July of last year.
De Ligt is very happy to be a player for the club.
One of the most successful clubs in Europe and in the world is FCBayern.
The genuine appreciation from the sporting management, the coach and the board convinced me. It's a brilliantly run club with big goals.
I'm very happy that I'm now a part of the FCBayern story.
De Ligt had one title and one trophy in his career.
He became the second Dutch player to join the club this summer after Ryan Gravenberch's transfer to the club.
Sadio Mane, a right-back, and Noussair Mazraoui, a right-back, have joined the club.
