We’ve not been the same league as them, literally and metaphorically, for more than 20 years. Growing up from 65 to 80 we were only in the same league as them for 2 years, whereas Cardiff we seem to play more or less every season. Plus Cardiff have similar facilities and more or less the same level of fanbase.
If you ask a Forest fan who are their biggest rivals, Notts County or Derby. I guess the majority would say Derby. And so it is for me with Cardiff, although there’s no denying the gas are a poxy wee club id love to see go bust.
