The club provides free videos of training, and Aguero was not there. I can't make it any clearer than that. He was not training with the rest of the squad. Iheanacho was. Therefore Iheanacho was available for selection. Aguero seemingly far less so, since not training is reason enough not to select him. As is the rotation of a key player, like De Bruyne today. That also doesn't apply to Kelechi. Again, totally different situations with regards to their non-selection. You're exaggerating by saying I'm insinuating his personal life is "falling apart". That's just sensationalism.
