Former Tottenham boss Andre Villas-Boas has no doubts about the quality of Ajax midfielder Frenkie de Jong.

De Jong will move to Barcelona at the end of the season.

AVB told Voetbal International: "He's incredible. I like players who are above average when it comes to technical and tactical ability. The players who help form others around them.

"De Jong has that technique, the same as players in the class of Van der Vaart and Sneijder. He's one of those players who controls the ball and has that classic Dutch style."
