The agent of Viktor Fischer is baulking at discussing new terms with Ajax.
The young Dane attracted enquiries from Manchester United and Chelsea over the summer and remains high on the agenda of both Premier League giants.
Ajax are offering a two-year extension to his current deal, which expires in 2014, but agent Soren Lerby is in no rush.
"We'll take it easy," said Lerby. "We have to be smart.
"First we want to talk about the first team chances for Viktor. We'll wait until the winter (January)."
