AS says Real will consider Pochettino and Castilla coach Raul as their next manager if they decide to sack under pressure Zidane.
Real suffered a shock 3-2 defeat to Shakhtar Donetsk in their Champions League opener on Wednesday after being 3-0 down at half-time and they were also beaten by LaLiga new boys Cadiz last weekend.
Real president Florentino Perez could consider Pochettino and Raul as possible replacements if they part company with the Frenchman.
He insisted Raul returned to the club to take over as manager of their reserve team Real Madrid Castilla after spending time as a LaLiga ambassador in the United States.
Raul has been impressive since taking over the youth team but AS say there are doubts as to whether he is ready to make the step up.
Another option is former Tottenham boss Pochettino who has previously been linked with the job.
