Keeping the tradition for me, no question.
Furthermore, selling the club's soul is by no means a guarantee of success on the pitch. I chatted to a couple of Cardiff fans a year or so ago and their view was 'he's putting a ton of money in so I'm right behind him'. Problem being, how far does that extend? Sure, you might be happy to deal with the colours changing, the badge changing, but what about the name? The location? Once you sell out to a man interested in his own personal image in the far east there's no telling how far he'll go. And for all that uncertainty, what do they get? A promotion and swift relegation.
I'd guarantee a fair few of our fans would have taken a colour change to get Sisu in back in 2007. Look how that's worked out. There are no guarantees in football.
The Cardiff-going-red thing pissed me off for a whole number of reasons, not least that it was the embodiment of a footballing society that doesn't care about it's roots. 20,000 people turn up to watch Cardiff on a matchday. Ultimately that's nothing in the world of English football though. The money is made by getting a club to the Premier League and marketing it worldwide. In a game that's driven by cash, the clubs that care about their roots and their local support get trampled on and left behind.
I read the other day that Liverpool estimate that they have around half a billion fans worldwide. The 40-odd thousand that show up at Anfield, buy a shirt, hold a scarf and sing You'll Never Walk Alone do not matter a jot. The vast majority of the income will be from the 499,960,000 other fans around the world. English football, the Premier League in particular, is now the world's game, with no meaningful links to its roots. Until something like Germany's 50+1 is introduced that will remain the case.
So yeah, tradition please!
