Ajax midfielder Christian Eriksen cannot guarantee staying beyond the end of this season.

The Dane is tied to Ajax until 2014 and has Manchester United, Manchester City and Arsenal on his trail.

"I have not said no, but I want my options open when a moment comes when it feels the right time to leave," said Eriksen.

"I understand that the club wants to extend my contract, but I also feel that there comes a moment that I want to make the next step."
