Yeah I've got concrete proof that he's made an incorrect decision (like plenty before him) for short term gain rather than looking at future progress, as Sancho did. He was told he would not get time and left the club, much to his benefit.
You have no past track record of developing youth players, what more concrete proof do you need that players won't get given time with you? Nobody has and nobody will, because Pep need only click his fingers and bring in a 50m replacement without a second thought. You remind me so much of Chelsea fans who were so sure that their brilliant academy would bear fruit, but like all money clubs you have no real interest in actually giving opportunities to these players if it comes with even the smallest of short term risk.
I wonder how many minutes Foden will get today. 5? 10? If he's lucky. Most likely Saint Pep will bless him with a couple of minutes at the end, might even touch the ball.
