Ajax will only sell Newcastle, Spurs target Toby Alderweireld for huge money
The reigning Eredivisie champions are reluctant to see another product of their famed academy system head for the exits midway through the season.
On the transfer rumours, coach Frank De Boer said: "That's maybe something for next year.
"I think he'll end this season at Ajax.
"We're very happy with him and don't want to let him go in the winter unless it's a super transfer fee, but I don't think that will happen."
