Directors from both clubs met on Sunday for the Classic Match, a charity game involving veterans of both sides at the Bernabeu and are believed to have discussed the future destination of the Argentina international.
Higuain revealed to the media after the last game of the season that he wished to leave the club, which he joined from River Plate in January 2007.
However, the Madrid hierarchy are understood to be against making any further decision without the approval of the new coach.
The favourite to take over from Jose Mourinho in the Madrid hotseat is the former Juventus boss Carlo Ancelotti, who is still under contract with Paris Saint Germain.
Juventus director general Beppe Marotta told reporters: "Real Madrid have told us that Higuain is not for sale and that no decision will be taken before the new coach arrives."
Madrid are understood to only be willing to listen to offers starting at 25million euros (over £21million) for the 25-year-old, who has also been linked with a move to Arsenal.
