One person then, by the sounds. For all I dislike Liverpool, there is loads of similar stuff at NUFC games.
Not a coincidence this has happened this week though. Liverpool FC and in particular KKK have created this situation with their actions over the past fortnight. Presumably they'll be in support of this supporter too now, get the t-shirts printed.
If the FA want to maintain credibility with the Kick It Out campaign, they need to take action against KKK and the club imo.
