However, he has now opened the door for a future move to United and their rivals after admitting that a move to England appeals him.
Jose Mourinho supposedly told the youngster, son of former Barcelona and Netherlands forward Patrick, following the Europa League final that he wanted to bring him to Man United in the summer of 2018.
Young Ajax winger Justin Kluivert admits he would find it hard to turn down a move to the Premier League, while Barcelona are also intriguing.
"If you get a nice offer, you never know", Kluivert, whose deal runs out at Ajax in June 2019, told Helden.
He's kicked on even further this year, playing regularly for Ajax and demonstrating his considerable ability with a fantastic hat-trick in November against Roda JC. Arsenal, Tottenham, Chelsea or Manchester United are nice clubs where I can see myself playing in a few years.
The younger Kluivert has burst onto the scene lately, having excelled in glimpses in 2016-17.
The World Cup certainly makes it a more interesting summer - some players will want to wait until after the tournament when they've been in the shop window, others will want their future sorted early to remove distractions.
Ajax are aware that some of the top clubs in Europe have been keeping close tabs on Kluivert for a while, with Manchester United believed to be interested in signing him. Getting regular football and developing at Ajax, for another season at least, is surely the smartest course of action at this point.
