The PSG star posted a cryptic message to Twitter about his former Barcelona team-mate, saying to "stay tuned".
Something big between Neymar and former Barcelona team-mate Lionel Messi is apparently about to happen.
That is according to Paris Saint-Germain star Neymar, who left Camp Nou last August for a record €222 million deal with the Ligue 1 giants.
Neymar – recovering from a fractured foot ahead of the World Cup in Brazil – posted a cryptic message to Twitter on Sunday.
