Tan probably "invested" more in Cardiff in the first 2 seasons than the Holywood actors have spent at Wrexham since they've been there.
Tan started off changing the Cardiff shirts to look more like a Wrexham home kit, than anything that resembled the club. That pissed off a load of fans, those who decided to stop supporting the club were told by fellow fans like
@Dr. Lecter that there'd be plenty of fans queuing to replace us. Funny thing was, for a few seasons after the PL flop I was getting e-mails from the club telling me my old seat was still available and would I like to come back.
I'm amazed that Tan gets away with being a shite owner, unless you lose a few games when people start whinging. Wrexham fans haven't, yet, had a need to boycott their club, and they are actually picking up fans from all around the world. Even, sad to say, the South Wales Valleys. Tan couldn't even get a single fan from his home country to become a redbird but, IIRC, some armchair fan(s) tried to cash in by creating a forum called the redbirds, where every cuckold that had stepped into Ninian Park (whether for a match or a hog roast) , so he won over the people that mattered.
