As someone else pointed out all clubs are selling clubs Man City make significant sums selling young players it’s getting to the point when it’s not disruptive to the first team.
Although surely you can see that’s evolving again at a sensible level. Buying Pedro and Beleba at nearer £30m than £4-10m paying £160k a week wages to Fati.
To progress we can’t rely on plucking a gem and it seems the club want continued success.
