Experts of last DAILY TOPIC: If you were Zidane, why would you leave Real Madrid? 

@Dannydrexx: I will leave so as to keep my image clean ......since Perez has become so unbecoming by trying to cheat Ronaldo will fake promises ,,,,and also trying to bring Neymar and sending Ronaldo away in fact ,,,I will leave because Perez is an ingreat.

@Laity Council: It's simple the man had to leave cos he is scared luck won't favour him this time around.Truth is he's just lucky he met a readymade world class squad in Ramos,Ronaldo,Marcello, Modric,Carvajal,Kroos who are arguably best in their respective positions etc.he's no expert to be frank.If you doubt me think of any major decisive decision he made like guardiola the boss.He only sold stars out and bought low profile players who were useless to the club.His next destination will testify to the fact that he isn't really the expert good luck has tried to make him look like.Like it or not it's the truth.

@samingo: Personally, I think Zidane left because Perez wanted to do a swap deal with PSG by bringing neymar in for Ronaldo but Zidane sees Ronaldo as irreplaceable, at least , for now. if neymar couldn't do it at PSG with all the freedom he had,then I'm afraid, he can't do it in real Madrid. His unnecessary dribbling and overspending more time on the ball won't favour Madrid's style of play.

Probably, Perez put undue pressure on Zidane to agree with the signing of neymar and he had no other choice than to back out because Zidane has absolute trust in his players. Ever since Zidane took over at Madrid, he has not brought any major signing in the team,just to keep egos in check and keep the players motivated to do even more.Once a big ego player like neymar is brought in,it may unsettle the atmosphere in the team and dat will be the end of Zidane so he acted fast by predicting his immediate future and backing put.
