Despite back-to-back Champions League titles and recent recognition at the FIFA Best awards, pressure is mounting on Zidane after a disappointing start to the 2017/18 campaign.
Los Blancos look set to only qualify in second place from their Champions League group, while poor results have seen Barcelona open up a 10-point advantage at the top of La Liga already. The most recent setback came in the form of a 0-0 draw in the Madrid derby against Atletico.
Real president Florentino Perez has famously had little patience with the Frenchman's predecessors. But while Don Balon claims the Bernabeu chief retains confidence in Zidane given his remarkable achievements in a short space of time, he does not want to be left unprepared.
As such, the Spanish gossip outlet suggests that Perez has settled on Low as a summer replacement if things do not improve for Zidane in the rest of the campaign.
Don Balon claims first contact with Low, 57, has been established and that he is 'delighted' by the prospect of making the move to Madrid.
His reputation as a coach is vast, but a concern for Real fans may be that his previous club experience isn't half as impressive. Low hasn't coached at club level since 2004 when he left his role with Austria Vienna.
He'd earlier managed in Turkey and his native Germany, with his highest profile jobs coming at Fenerbahce and Stuttgart in the 1990s.
