Yes but we have to have to have some kind of quality filter on the issue, I mean how much can you learn about the quality of a club's academy by the number of players they have developed for Wales or Ireland or Zimbabwe, not exactly powers in world football are they? I would suggest the acid test is number of full England internationals. You're right Lennon was at City, where he was failing, he then moved to Crewe and after working under Gradi went on to win the league cup twice with Leicester, 5 SPLs with Rangers and become captain of his country. Similarly with Platt and Savage, who were both rejected by United as youngsters but after working with Gradi went on to highly successful careers, in the case of Platt, successful being an understatement.
Celtic I should say.
