The reigning Eredivisie champions are reluctant to see another product of their famed academy system head for the exits midway through the season.
Ajax will not stand in the 23-year-old midfielder's way if he opts to take on a new challenge further down the line, but believe he would benefit from seeing out the 2012/13 campaign in Holland.
Coach Frank de Boer has made it clear that any club planning to make a winter move will have to dig deep in order to push a deal through.
He does not see Spurs or Newcastle United, who have also been linked, stumping up the cash and feels the Premier League will have to wait a little longer before adding yet another talented Belgium international to its ranks.
On the transfer rumours, 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."
