Ever since the goalkeeper succeeded Iker Casillas as Madrid's No.1, his place has been on a shaky peg as the club have constantly been linked to bigger names.
And the Belgian's winks to the Spanish giants have only enhanced expectation that he is heading for the Santiago Bernabeu, putting Navas' place in further doubt.
On Thursday, Navas made an unusual post on Instagram that could be a hint that he is saying farewell to Madrid fans after four years there.
The 31-year-old shared a video that showed the club lifting the three Champions League trophies followed by a display of all of the trophies he has won since joining from Levante in 2014.
If it is not a cryptic farewell message to supporters, it could be a reminder to new coach Julen Lopetegui and the club's hierarchy that he has shown his worth after 141 appearances.
