== Relevance? == 

 Of course it is relevant. The Laws of Association Football (Law 4) state that the kit colours of the officials must be distinguishable from all other players, including the goalkeepers. It is the referee's sole duty to ensure this, not the match assessor or home club/away club. 

 If necessary, the referee and his assistants change their coloured shirts to ones which do differentiate. Therefore, in the context of a biographical article such as this, it does become notable if the referee fails to carry out his duty (which unfortunately Howard did on this occasion). 

 However, I do admit that it is an ever-increasing sight to see goalkeepers' and officials' garb clashing so obviously!  

 By the way, Howard's three red cards in one match is not the same as a total of three red cards in all previous League Cup Finals - so both statistics should be quoted in the article. And trying to apply "relevance" to a section headed 'Trivia' is like stepping on quicksand.
