Which club has the most promising youngsters?

When it comes to youngsters, Arsenal always wins the award for the most promising youngsters. The only problem is I don't know if you mean what team has the most promising home grown youngsters, or what team has the most promising youngsters on the rooster. Arsenal's youngsters are almost never a product of their youth academy. Wenger knows how to raid other team's academies getting the best young talents available. The Arsenal squad is run by youngsters, even Fabbregas is only just 23, even though his skill level and experience would easily make people exclude him from that clification.
