Former Real Madrid president Ramon Calderon says Zinedine Zidane has been asked about returning.

Santiago Solari isn't expected to survive after Real's Champions League elimination by Ajax.

"I know that this [Wednesday] morning the president [Florentino Perez] called Zidane to ask him back; he said not now," Calderon, who was president from 2006 to 2009, told BBC Radio 5 Live.

"He has left open the possibility of coming back in June.

"They are talking of the possibility of Zidane or (Jose) Mourinho - they are completely different coaches with completely different ideas of football.

"It is an erratic and whimsical president who has brought us to this situation.

"There is the option of bringing in Mourinho now, but to me there is no point.

"At this moment of the season anything you do is going to be wrong. I suppose that they will wait until the end of the season, but this is very long time - three months - to suffer all the critics and the anger of the fans."
