He joined when we were shit and he was still a very good footballer, he scored loads, got us promoted and connected with the fans. Then, as a manager, he joined us when we were shit, got us scoring loads playing great football, got us promoted, connected with the fans, took us from almost relegated to what is now League 1, to genuinely challenging for the top flight title. Plus his familial connection with the club. Of course Keegan is adored by Newcastle fans, it would be weird if he wasn't.
Robson turned us from midtable mediocrity into a genuine title challenging side, playing some great football, with really exciting young players. Connected with the fans in a way not seen since Keegan. Plus his familial connection with the club.
If Henderson retires from playing, becomes your manager and lifts you back to the Premier League, without winning a single proper trophy, there'd be calls for him to get a statue and you're lying to yourself if you think that's not true.
