Xavi knows all about playing at the top level, having made 767 appearances for Barcelona, winning eight La Liga titles and four UEFA Champions League crowns during a glittering career in Spain.
The midfielder, who now plies his trade at Qatari club Al Sadd, previously played with Neymar for two years during his time at the Nou Camp, winning the European Cup together in 2015.
And Xavi believes the Brazilian, along with new Paris Saint-Germain team-mate Kylian Mbappe, are the future superstars of world football.
"I think there will be a while after Messi and Cristiano [Ronaldo] when Neymar will be the reference point," the midfielder told El Pais.
"Especially as he is Brazilian; Brazil have every chance of making it to a World Cup final.
"The Neymar era will last three or four years, and then Mbappe's time will come. He has mad potential.
"And he is still young; he's only 19. He is a monster."
