As the current coach of Real's second team and having turned out for Los Blancos as a player, Zidane has the benefit of knowing the club inside and out. However, it would be a massive gamble to hand the Frenchman the reins considering he has never managed a top-level side.
Zidane is likely to make the step up a senior club soon, but it seems unlikely that his immediate destination will be the Bernabeu dugout.
The Spaniard's two-year contract with Napoli has expired and his future at the Serie A club is unclear, meaning that he should be easily available should Real decide he is their man.
While Zidane lacks experience, Benitez has a mass of it, having achieved success in Spain, England and Italy. Whether Benitez is deemed to have the flair to match his experience remains to be seen,
Having started both his playing and managerial career with Real, Benitez has a close connection to the club, and being a friend of Madrid's Director General, Jose Angel Sanchez, certainly won't hurt his cause.
Like Benitez, Klopp is available, with the German having parted company with Borussia Dortmund after seven years at the helm.
While Klopp's tenure at Dortmund will certainly be remembered as a hugely successful one, some doubts regarding his abilities began to emerge during a testing final season in which Dortmund spent time in the relegation zone.
Klopp's success has come managing a plucky underdog side, and Madrid are anything but. The test for Klopp would be making the adjustment to a club where titles are not negotiable, just against Ancelotti…
The FC Porto boss has been getting a lot of airtime in the Spanish press, with favourable reports emerging from publications more renowned for tearing managers apart than delivering lofty praise the likes of "young and hungry" with an "adventurous, daring style of play".
The Spaniard gained many plaudits for the manner in which he set up his team in their 3-1 victory over Bayern Munich in the Champions League. While they couldn't back that up with a victory in the second leg of the tie, it gave a clear indication of Lopetegui's tactical nous.
Linked with a move to AC Milan, Emery could be appealing prospect for Real given that his successful record in Spain and in Europe, with a second consecutive Europa League title still on the cards.
After leading Benfica to back-to-back Portuguese Liga titles Jesus may fancy it's time to step up to a bigger challenge, and there are few bigger than in Madrid.
However, there may be some uncertainty regarding whether Jesus has the pedigree to achieve immediate success at the Santiago Bernabeu.
