Rafael Van der Vaart is backing Ajax midfielder Frenkie de Jong for success at Barcelona.
The former Real Madrid and Ajax star has no doubts about the potential of De Jong.
"He creates a lot of goals and, with the ball, he is the best player in the Netherlands," enthused Van der Vaart.
"I think that Barca is the best team in which he can be."
De Jong will move to Barca at the end of this season for a fee rising to €86m.
