#1 Real Madrid

Jose Mourinho managed Real Madrid for three seasons between 2010 and 2013 and while he had the most expensive squad in history during his spell in charge, he did not leave on the best of terms, having failed to break Barcelona's hegemony and fallen out with key players at the club.
The manner in which he fell out with players in the dressing room might represent a snag to his return to the Bernabeu, especially as one of the players who he fell out with - Sergio Ramos remains at the club.
The Real Madrid captain wields such power that he was instrumental to Conte not getting the Madrid job having been in pole position following Lopetegui's sack when he stated that 'respect is earned not demanded'.
A factor in favour of Mourinho, however, is the respect of club president Florentino Perez still possesses for him and reports from highly instrumental figures within the club suggest that the Madrid supremo is lining up a move for him to return to the Bernabeu.
