#3 Zidane has never overcome adversity
As a manager, just as he did as a player, Zidane has thus far been massively successful. After taking over from Rafael Benitez in 2016, he immediately won the Champions League, and in 2016/17 he went one better by winning both La Liga and retaining the Champions League.
But everyone knows that you can’t succeed all the time, and 2017/18 is basically the first bit of adversity that Zizou’s faced as a boss.
Where before he could always rely on the insane talent of the Real squad to come out on top in bad situations, that simply doesn’t seem to be the case anymore. Cristiano Ronaldo hasn’t been scoring nearly as many goals as he once did, Sergio Ramos looks past his prime at the back, and Gareth Bale has spent the majority of the season on the sidelines.
Other, more experienced bosses like Jose Mourinho and Carlo Ancelotti had dealt with plenty of adversity at other clubs by the time they arrived at Madrid, and thus when things went wrong, they knew how to go about fixing them.
Zidane simply doesn’t have that kind of experience and thus he’s way out of his depth this season – and that’s why Madrid simply must make a change and get rid of him.
