Why would we want a former player to do well ??
Because the players are the club. It's only the players that we care about. If they're pushed out by club employees against their wishes or reasonable market value, we don't turn on them. We want them to do well because it's them that we've been emotionally invested in.
I know there's the likes of you that support the off-field employees and as soon as they force someone out then it's a stacks on scenario. Some of us see the footballers as the club, not the support staff. Each to their own though.
