De Jong, 21, is one considered as the brightest midfield prospect in European football at the moment following his rapid development with Ajax since his arrival from Willem II in 2015.
A cultured midfielder, whom Barcelona club legend Xavi claims has 'the Barca DNA' in his blood, has been touted for a big-money move in the current transfer window.
The Blaugrana, City and Paris Saint-Germain are said to have enquired over his availability before Ajax set a price-tag of €75m for the Netherlands international to ward off their interest.
However, with the LaLiga champions undeterred by their demands, De Jong has now come out to clarify his future with de Joden, who are currently in the UEFA Champions League knockout stage for the first time in 13 years and chasing their first Eredivisie title in five seasons.
"I am certainly not leaving this winter," De Jong said, as per ESPN FC. "I am 100 percent staying until the summer [the end of the season].
"I don't know what other people are doing, but personally I would like it if the whole group stay together. We have had a fairly decent first half to the season.
"The atmosphere in the group is very good and we have a lot of quality -- so I would be disappointed if people left."
