They say you should never go back. But in football management, sometimes it's best to go with what you know.

Monday's announcement that Zinedine Zidane has agreed to become Real Madrid manager for a second time less than 12 months after stepping down came as something of a shock.

The Frenchman guided the Spanish giants to a historic three successive Champions League titles before relinquishing his post on May 31, 2018. But with the club parting ways with Santiago Solari, who only succeeded Julen Lopetegui, Zidane's replacement, in December, following a shocking run of results that included back-to-back defeats to Barcelona and a humiliating Champions League exit to Ajax last week, Zidane answered Madrid's call.

He is certainly not the first to defy the "never go back" theory. Indeed he isn't even the first ex-Madrid manager to do so. Here is a look at others who have returned to their former flames with varying degrees of success.
