The Holland international has recently been linked with the likes of Valenica, Chelsea and Manchester City.
Ajax recently turned down a bid from Valencia for the full-back.
“Ajax has business as well as sporting considerations to take into account, but in the case of Gregory it is clear that in the winter he is not likely to go,” Blind told Ajax’s official website.
“Coach Frank de Boer and his staff discuss will discuss this matter. We will talk to the player himself, or his agent, to find out what he wants.
“Gregory is important to this team. If Valencia or any other club want to sign him in the summer then, of course, if the price is right then it will be considered.”
“The bid Valencia offered was too low and, in our view, showed little respect for Gregory especially given his track record and enormous potential,” Blind said.
“Despite still only being 23 he has become an important part of the Ajax team and is a fixture with the Holland team that reached last year’s World Cup final.
“Ideally he will remain and enjoy more good times as is possible with a player who has grown up at a club and progresses to do well in the first team.”
