Like comparing your current girlfriend to an ex who didn't want to be with you anymore,you torture yourself over the past when a bright future awaits. Nobody knows how Cole would have done if he stayed, but he is GONE. He's dancing with a rival, and didn't want to stay with you...LET IT GO!
I think Oscar has as high a ceiling as any of them, and I hope he gets the chance, but to have Doku, Savio, Oscar Bobb, Claudio Echeverri, Rico Lewis, and Phil Foden as the creative young setup of our team should set any City fan's pulse racing. The future could be well and truly golden. The potential is HUGE!
