The Dutchman, who has been linked with City in the past, is currently closing in on his third league title at Ajax.
He admitted, though, that he would not be taking over this summer.
"Manchester City is something I want to do, yes," he told The Mirror.
"But it is difficult for me to move my family abroad at the moment. I have to consider others not just myself."
Ajax director Marc Overmars also admitted that City could come in for his coach in the future.
"Am I worried? Not for losing Frank now, but City will be a big competitor for his signature in the future," Overmars said.
Ajax are currently two points clear in the Dutch Eredivisie with a game in hand.
