Paris Saint-Germain have completed the signing of defender Abdou Diallo from Borussia Dortmund for a fee of €32 million including bonuses.
As confirmed by ESPN FC sources, the France under-21 international successfully underwent his medical in the French capital on Monday before signing a five-year contract at Parc des Princes.
"It is a great honour to be involved with such a prestigious club as Paris Saint-Germain," Diallo said. "I have always said that the Parisian project was very attractive.
"Joining the capital club today is another important step in my career. I am committed to giving my all for my new club and look forward to bringing my qualities and desire to this team renowned for its high quality and high ambitions."
Diallo, 23, left PSG's Ligue 1 rivals Monaco for Bundesliga outfit Mainz back in the summer of 2017 before joining Dortmund for €28m the following year.
After another season in Germany, he is returning to France at coach Thomas Tuchel's request following the failure to land Ajax defender Matthijs de Ligt ahead of Juventus and Barcelona, according to sources, as well as Kalidou Koulibaly.
Sources have told ESPN FC the Ligue 1 giants consider the signing of Diallo a coup at €32m and the move allows sporting director Leonardo to concentrate on securing a defensive midfielder of high quality.
PSG now boast Marquinhos, Thiago Silva, Presnel Kimpembe and Thilo Kehrer, as well as Diallo, as senior central defensive options -- although Tuchel is disappointed with Kimpembe's attitude and Silva is entering his final 12 months of contract.
