One possible English destination for De Boer is Newcastle United, who are looking for a replacement for Alan Pardew, but the Dutchman insists any move would have to wait until the summer.
"I only said if they asked I don't go because I am now with Ajax and I don't want to go halfway (through a season) while also stepping into a team that are already halfway too.
"So for me, if there will be a chance it is always in the new season."
Asked if he would consider a move to St James' Park next season, he said: "I have everything open... but I will be ready, that's for sure."
