Neymar broke the news that he was leaving Barcelona for Paris St-Germain at Lionel Messi's wedding, according to his former team-mate Xavi.
The Brazilian moved for a world record fee of 222m euros (£200m) in August, after four seasons at the Catalan club.
Neymar and Xavi, who played together for two years at Barcelona, attended Messi's wedding in July.
Xavi also told the BBC World Service he turned down Manchester United because Barcelona was his "favourite team".
Former Fifa president Sepp Blatter has accepted an invitation from Russia leader Vladimir Putin to attend next year's World Cup. Blatter's 17-year spell in charge of world football's governing body ended amid a corruption scandal in 2015.
Fifa subsequently banned Blatter from the sport for eight years, a term later reduced to six years after appeal.
"I will go to the World Cup in Russia," said Blatter, 81. "I received an invitation from President Putin."
