You've completely missed the obvious reason we want to see it.Sick of reading kids should be playing, if Pep thinks they are ready they'll play. This is City now not City from the 80's and we are one of the best teams in the world so they have to earn it
This was a pointless game, the main players know it's pointless, they were never going to go 100%.
But the kids know this is their rare chance to impress the boss and would go full throttle, what kind of manager wouldn't give this chance to a youth player when its so easy to do so.
The easy counter argument is "Well some of these players need minutes for United", but then why they did play 90 minutes? Why does he complain about subs?
He is confounding.
