Belgium international Jan Vertonghen has been linked with a move away from Ajax

Transfer news: Jan Vertonghen is focused on Ajax but admitted the situation is difficult

Tottenham target Jan Vertonghen would like his future to be resolved as soon as possible but insists he will continue to give 100 per cent for Ajax.

The defender returned for pre-season training with the Dutch giants but Spurs are locked in negotiations over the Belgium international and it is likely he will move to London in the near future.

“Of course it goes through my head that there is still no clarity about my future,” the Belgian told Ajax’s official site.

“It is difficult and I can’t say I don’t think about it but that’s how it is and I have to adapt. For now I play for Ajax and I will always give 100 per cent for them.

“I am a professional athlete and despite all the issues for me it is simply the beginning of a new season. And that, for me, starts at Ajax.

“It is obviously impossible to say how long these things take but well before August 31 (the closing of the transfer window) there must be clarity.

“Until then I will just focus on Ajax.”
