It’s an interesting dichotomy.
On the one hand, it’s not good for the future of NSD (in any format), that a major clubs fans are not participating.
But on the other hand, their boycott shows they care. And that this tournament matters.
However, and without knowing anything about the background on this issue, the persistent police/security presence is a big problem. It appears the authorities are hell bent on clamping down on any perceived anti social behaviour.
Having said that, I cannot say I’ve seen any obvious security presence at South games. ESPECIALLY against Preston.
