Zidane does'nt like him and told him he does'nt want him at Real which is the Manager's option just like your great Coutinho was not wanted at Barcelona ;-)
Real are trying to reduce expenses and wage bill just like all clubs at moment similar to Barcelona
ie the reason they have your coutinho out onloan !
Coutinho lost his place to Muller who is in twilight of his career :-(
Munich are a highly efficently run club with finances etc and changed Managers when Rodriquez was there who decided against taking the option to buy him just as your world class coutinho option has ot been took either !
In my opinion, Coutinho is a poor mans Rodriquez, he was a 1 game in ten top class performance while at redshite ! For less transfer and wages and for international attention Rodriquez would be a better option ;-)
