I liked the first two categories, but the problem with having 8 football clubs is there are loads of different ways you could group those accurately that weren't the answer you were looking for. E.G. Four of the clubs are Premier league and four are lower league, but this wasn't the answer.

Always happy to see football in the grid, but agree with SB about other potential answers. For me the Liver bird badge also complicated things even when I got close.
