10. Manchester City – Joe Hart
Debut: October 2006
He’s currently out on loan, but no player registered to Manchester City made their debut earlier than Joe Hart. Then still a fresh-faced teenager, the young stopper was called into action in the autumn of 2006 after injuries to Andreas Isaksson and Nicky Weaver.
Of the players actually in Manchester, Vincent Kompany, and Pablo Zabaleta both joined in the summer of 2008 – just days before Sheikh Mansour completed his high-profile takeover.
