It'll come to down to if Iker plays against Granada? Carlo to do the right thing? What is that supposed to mean? He's doing what's best for the team now, playing a better keeper. Iker can't take that heat of competition? Get out of the kitchen son.
Even if the rumors are true, which they're not, and it's hilarious how they appeared in a matter of a day or two, Diego is not going to play forever and if despite that Iker is upset then fuck his mood swings.
