5 reasons why Julen Lopetegui shouldn't have accepted the Real Madrid job

#4 Perez' fractured relationship with managers

Perez has a notorious history of firing managers rapidly

Florentino Perez is the billionaire president of Real Madrid, and his policy of changing coaches as quickly as they come in is well known throughout the world.

Perez runs a tight ship at the Bernabeu, and his role as Judge, Jury, and executioner means that he controls the key decisions in policies such as player transfers and coach's hiring or firing.

He has had two spells at the club, the first of which lasted from 2000 - 2006, and saw six coaches revolve through the manager's door at Real, including a period in 2004 when Real Madrid had the ridiculous record of having three different coaches in just three months, with the result being that the club lacked stability and underwent a three year trophyless period, and underperformed in the UCL.

After resigning in 2006, he returned for a fresh stint at the presidency in 2009, and while there have been many improvements in terms of silverware, a similar factor has been the frequency of coaches.

Santiago Solari (Lopetegui's temporary successor) is the seventh manager Real has had in the nine years of Perez' second term, and off the six before him, only Zinedine Zidane left on his own terms, with the rest essentially being pushed out.

Lopetegui ended his reign at just 14 matches, which is the second shortest since 1929, and there would be no prizes for guessing they the shortest reign also came under the 71-year-old, when Jose Antonio Amacho resigned after just five matches, and this unfavorable factor for coaches is a reason why Lopetegui would best have stayed away from the role.
