Carlo Ancelotti has taken over as Real Madrid manager, with Laurent Blanc replacing the Italian as coach of Paris St-Germain.
Ancelotti, led PSG to the French title last season but asked to leave the club in May after Real made an approach for him.
He has signed a three-year deal in Spain to replace Jose Mourinho, who left to become Chelsea boss.
Blanc, 47, has agreed a two-year contract at the Parc des Princes.
PSG appeared to be trying to secure a replacement for Ancelotti before letting him go and said they were "delighted" at Blanc's appointment.
He will take charge of the squad on 1 July for the start of pre-season training.
Blanc played for Montpellier, Auxerre, Barcelona and Manchester United during his playing career, and he was also part of the French side which won the 1998 World Cup and Euro 2000.
