Urby Emanuelson is being chased by a number of clubs from across Europe, according to the player’s agent.
With his contract set to expire at the end of the current campaign, the 24-year-old will therefore become a free agent next summer.
"There is quite a lot of interest," Brian Berkleef said in De Telegraaf.
"I won't say anything about the clubs that are interested. However, I can confirm that I have told all the clubs that we won't do any business before January."
While Emanuelson is prepared to weigh up his options at the turn of the year, Berkleef has ruled out the possibility of a move being pushed through at that time.
"A transfer in the winter break is not an option," he said.
"He wants to leave Ajax in a good way, hopefully with a title and he will put in 1,000 per cent to help make that happen."
