Brazil captain Neymar moved to Camp Nou from Santos in 2013 and has two seasons remaining on his five-year contract.
Talks over a new deal have continually stalled, with links to Paris Saint-German, Manchester United and even Real Madrid subsequently surfacing.
While Ribeiro insists Neymar is happy at Barca, he claims there are three teams primed to activate the buy-out clause in the forward’s contract.
“There are three big clubs in the world that want to sign Neymar and pay a clause of [approximately] €200m to Barcelona,” Ribeiro told Radio Jovem Pan.
“I cannot say more than this because it is confidential.
“I can only guarantee that Neymar is happy in Barcelona.”
