That approach isn't consistent with your point: "People who think these guys have some kind of miraculous talent judging abiity, are just fucking stupid, & going against all evidence."
Sorry, I just don't think you're making sense. You're saying that Pep has no ability to judge but you're also saying let him pick the best ones in his opinion.
Regardless: my point is that you don't have to put them in the first team to find out. You just let them train with the first team players and see if they're goos enough to hold their own there.
