Neymar completed his world record transfer to Paris Saint-Germain on Thursday when he signed a five-year contract, the French club announced.
The 25-year-old Brazilian earlier broke his contract with Barcelona by paying a 222 million-euro ($264 million, £201 million) buyout clause.
“I am extremely happy to join Paris Saint-Germain,” said Neymar in comments posted on the English language version of the club’s website.
“Since I arrived in Europe, the club has always been one of the most competitive and most ambitious. And the biggest challenge, what most motivated me to join my new teammates is to help the club to conquer the titles that their fans want.
“From today, I will do everything I can to help my new teammates, to open up new horizons for my club and to bring happiness to its millions of supporters around the world.”
PSG confirmed that Neymar will be officially unveiled in a press conference at their Parc des Princes stadium on Friday at 1.30pm (1130 GMT).
