#3 The future of Isco
Why is Isco's future so important? Because at 26, Isco is very vital to Spain and Madrid's future, but he was being wasted away on the bench for much of this season.
Sure, Zidane used him but when you have a player like Isco, you do not merely use them but use them well.
It is no secret that Isco is a completely transformed player when playing for Spain - and it is all about the tactics.
In the national team, Isco plays more as a number 10 than as a winger, and has more freedom going forward - unlike at Madrid where he has to track back to defensive positions as well.
Under the same Lopetegui, Isco was responsible for Spain's crushing victory over Argentina, and this partnership at the club can only end up well for Madrid.
With rumors abundant that Isco was looking for a move away from the club in the summer, this appointment might just be necessary to tie him to the club.
It is much easier and better to hold on to Isco, who has proven to have the potential to be one of the best midfielders, than to spend a huge amount to procure someone else.
Admittedly, this might not be the reason for the appointment, but a natural part of it. Either way, Isco will be happy and so should the Madrid fans.
