The two-time World Cup winner is certain that the 21-year-old will be a star in La Liga after sealing a move from Santos to Camp Nou.
The 21-year-old star completed his move from Santos to Barca on Monday for a fee reported to be in the region of 60 million euros, signing a five-year-deal with the Spanish champions.
“Is Neymar ready? Absolutely. Neymar is 100 percent ready to play for Barcelona,” Cafu told Goal. “He is already a world-class player.”
Cafu, 42, enjoyed a glittering playing career, winning 142 Brazil caps and two World Cups while also claiming Serie A titles with Roma and AC Milan. The 2007 Champions League winner also played down reports that his former teammate Clarence Seedorf was ready to succeed Massimiliano Allegri as the coach of Milan this summer, though.
"Clarence is still a player so we can't talk about him being coach of Milan," Cafu said.
Seedorf departed Milan at the end of the 2011-12 European season to join Brazilian club Botafogo, but is said to be one of the favorites to replace the under-fire Allegri at the San Siro.
