Paris St-Germain have signed France forward Ousmane Dembele from Barcelona for £43.5m (50.4m euros).
Dembele, 26, joined Barcelona from Borussia Dortmund for £135m in 2017 and scored 40 goals in 185 games, winning three La Liga titles.
The 2018 World Cup winner has signed a five-year contract with the Ligue 1 champions.
“I am very happy to join Paris St-Germain and can’t wait to play in my new colours,” said Dembele.
“I hope I can continue to grow here and make all the club’s fans proud.”
Dembele, who also won the Copa del Rey twice, signed a new two-year contract at Barcelona last year.
Barca coach Xavi confirmed earlier this month that Dembele wanted to leave the club.
PSG president Nasser Al-Khelaifi said Dembele, who had a 50m euros release clause in his contract, would be an “important and committed player” for the French side.
He added: “The passion and determination shown by Ousmane as he has signed for PSG is fantastic and perfectly corresponds to the attitude required of all of our players.”
Dembele played in the World Cup final in December but a thigh injury meant he missed most of the second half of the season as Barca won the title.
He has been capped 37 times by France, scoring four goals, and is PSG’s ninth signing of the summer transfer window.
