As he believes bringing the player back to the club will be a good decision, Xavi also insists it will not be an easy job for Barcelona to secure the player's signature.
"He would be an incredible signing," admitted Xavi.
"But I see it as being difficult, honestly. I think it's very difficult.
"We have seen so many things that I thought I'd never see though, such as PSG paying 222 million euros, so we'll have to wait.
"There's no doubt that he's one of the best players in the world, but let's see what Barcelona do.

“We'd have to ask [Ernesto] Valverde [how he'll fit in]," Xavi added.
"He'll make the pieces fit. But if he signs it's because Valverde thinks he can play with the players there.
"Griezmann will be a spectacular signing."
Aside the rumours linking Neymar with Barcelona, Atletico Madrid forward Antoine Griezmann has also been linked with a move away from the Spanish capital to the Catalan city.
