"managed at the time by future Coventry manager Phil Neal", is this worth noting? If he had taken over following the final perhaps I would agree, but he wouldn't do so for another six years?
"beat fellow Division One", until now you've used the First Division, Second Division, etc format. I'd try to maintain the same style to avoid any confusion.
Perhaps worth noting that the two singles were "commemorative songs for reaching the final" or something similar just to explain the relevance of them to people who may be unfamiliar to the tradition.
First mention of Sillett outside the match details section. Worth including his full name and linking. Perhaps also list his position in the same way as Curtis also.
