De Boer, who has won three Eredivisie titles since his appointment at the Amsterdam ArenA in 2010, has been linked with the top jobs at both White Hart Lane and Anfield in recent years.
However, the former Netherlands international told the BBC World Football Show that he has previously turned down the opportunity to talk to the two clubs.
“Liverpool especially,” he said. “Tottenham called my manager with the possibility after sacking [Andre] Villas-Boas but I said, 'no, right now it's not the right moment'."
However, De Boer, who signed a new four-year contract with Ajax in the summer, went on to say that he would be more than happy to manage Tottenham or Liverpool once his tenure at the Dutch club comes to an end.
"Those two clubs are clubs that I think in the future I could be a manager of. I think the history of the clubs and what you can do with the team is my cup of tea," he said.
"I'm not really thinking about it because I'm very happy here at Ajax. I'm not in a hurry to leave because everybody is still happy with me.
"I step in my car with a big smile to go to the club. I don't think I'm finished here but there will come a time when I don't like it any more or the club doesn't like me anymore. Then we have to go both ways."
