The Spain international midfielder expects to meet the Brazilian side in the Club World Cup in December and has hailed the young forward, who has been linked to the Camp Nou
The 19-year-old Brazil international has long been linked with a move to Camp Nou, but recently declared his commitment to Santos by signing a new deal with the club.
"Neymar is a very talented player and he has an amazing ability," Xavi told Spor TV.
"There has been plenty of talk about a move to Barcelona or Real Madrid, but he recently renewed his deal with Santos. I think he can become a great player and can make a difference for any side."
Xavi could meet Neymar in the Club World Cup next month, and the Spanish star expects that Santos would be Barca's most likely opponents in the final.
"It looks like the final could be against Santos, but I am not sure. There are many good teams involved and so it will be difficult," the 31-year-old added.
