Santos have denied rumours that Neymar could be on his way to Barcelona at the end of the 2012/13 season.
Reports circulated that Barca had paid an initial 10 million euros for an unnamed player - believed to be the young South American - who would move to Camp Nou at the season's end.
However, the Sao Paulo giants have ruled out a sale of the Brazil international before 2014, when his current deal at the club expires.
"Santos reject any possibility of selling Neymar to Barcelona or any other team," a statement on the club's official website read.
"There are no negotiations under way, and the club reiterate that the attacker has a contract until 2014, which he will see out until the end."
The 20-year-old has won 25 caps for his country, scoring 16 times in the process.
