Why would the best team in the world promise x amount of game time to a kid thats barely started? Even our biggest names should be earning their game time, not promised a single minute.
He could have stayed and tried to forced his way into the team. If you're exceptional you will, as Foden did as a youngster. Rico is on the path to that.
Palmer didn't obviously fancy his chances and moved on, no problem with that. I think it was a good move for him.
But I just hope the club never use your method of promosing any raw kid game time.
