Tottenham manager Mauricio Pochettino has kept open the possibility of taking over one day at Real Madrid.
Pochettino is among the coaches being linked with the European champions, as the position of current boss Zinedine Zidane grows increasingly uncertain.
Real sit fourth in LaLiga, 19 points adrift of leaders Barcelona, and sank to a new low on Wednesday with a shock defeat at home to Leganes in the Copa del Rey.
Pochettino is familiar with Spanish football, having played and then managed at Espanyol, while Spurs collected four points off Real in this season's Champions League.
