The experienced coach is having doubts as to whether the tricky attacker will make an instant impact at Barcelona as he prepares to move to Camp Nou from Santos
The 21-year-old will make the move to the Primera Division champions this summer after they beat the likes of Real Madrid to the attacker's signature, but Clemente is not impressed with the hype surrounding the player.
"I don't really know much about Neymar," he told Sport. "I have only seen him on television. But there are a few things I do no like about him.
"I don't like the hype surrounding him. I prefer things to be simple and I don't like his haircut and his eccentricities.
"And the Brazilian league is nothing like Europe. When players from Brazil move to Europe, they generally need time to adapt. Neymar looks amazing on television and does some wonderful things, but football isn't that simple.
"Then again, if Barcelona are willing to pay that much for him and Real Madrid were after him as well, I imagine he's a good player."
Neymar will be presented to the press on Monday before taking off to participate at the Confederations Cup with Brazil.
