Neymar has become the most expensive footballer of all time after joining Paris St Germain for €222million.
The 25-year-old Brazil forward, whose legal representatives on Thursday paid Barcelona the world-record fee to terminate the contract which tied him to the Catalan giants, has signed a five-year deal with the Ligue 1 club.
PSG announced Neymar's arrival on their website just hours after Barcelona acknowledged the receipt of €222million, preceding the move's confirmation with a video posted on Twitter that teased: "He's coming."
Sao Paulo-born Neymar told psg.fr: "I am extremely happy to join Paris St Germain. 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 team-mates, is to help the club to conquer the titles that their fans want.
"PSG's ambition attracted me to the club, along with the passion and the energy this brings. I have played four seasons in Europe and I feel ready to take the challenge.
"From today, I will do everything I can to help my new team-mates, to open up new horizons for my club and to bring happiness to its millions of supporters around the world."
Barcelona have passed the details of the deal to UEFA. The fee obliterates the previous record of €105m that Manchester United paid Juventus for Paul Pogba last summer.
The Catalan club are keen for the governing body to "determine the disciplinary responsibilities that may arise from this case" with issues of Financial Fair Play and adherence to European transfer rules in mind.
Earlier in the day Neymar's lawyers were sent to LaLiga headquarters in Madrid to pay the huge fee, only to be snubbed.
France's own league body the Ligue de Football Professionnel (LFP) was quick to tell its Spanish counterpart to "abide by the rules", yet Neymar's team instead went to Barcelona directly to conclude the operation.
Neymar had indicated his desire to depart Barcelona, for whom he scored more than 100 goals, on Wednesday.
