Guardiola made some remarks about there being a huge gap between the academy and the first team which makes it difficult for him to transition players into the first team. That made immediate sense to me. And I thought it was quite good that he was honest about this problem. However you can still see as a Football Director the ages of your first team squad. Three of four years ago you should be planning ahead and bringing young players in, and then at 18 or so getting them a loan etc all for these moments in mindImo Marwood etc have done an absolutely fantastic job setting up the academy only for successive managers to use the kids purely as cannon fodder.
Too early yet to see if Pep is following on the same.
And if the players aren't there then you have your scouts working on every single prospect and you find out their circumstances, and before the transfer window you sit down with everyone and go through it all with every contingency covered. Perhaps we have all this in place, but I doubt it. The fact that we went for Alves in the first place suggested to me that there was no back up for Walker.
