To my knowledge there are at least 10 premiership clubs owned by foreign owners. One of them has changed the name. So 90% of them are not changing the name. Enough said?
Yes. It's pointless re-branding making them a laughing stock and it won't make a bit of difference on the pitch. The Crystal Eagles, sounds shit doesn't it.
You seem to be a little confused about the leap from nickname to clubname. All 92 clubs have nicknames and some have, historically, changed from time to time. Clubs have even changed their names in the distant past, but no team has gone the dreaded step to add the nickname to the clubs official...
sssSOCCERBAAALLLLLL!
I didn't know tigers were indigenous in Hull. They should have picked Hull City Goosanders, although they're mainly migrants (UKip are onto it)
