Just played this for the wife and her initial reaction was she says he's referring to Hillsborough as hooliganism. The second listen, she was a bit less sure, but then, as she then says, he's said "and other hooligan related" so to her that means he sees Hillsborough as caused by the same.
As others have said, words are his craft and he's been commentating since the 1970's, he knows exactly what he meant. If he wanted to keep them apart, all he had to say was "we had the Hillsborough disaster, we were having Hooligan related issues"
