There isn’t much history between Ipswich and Cambridge except for the 91-92 season. Although if that rivalry lasted beyond the one season it could have developed as the fanzines at the time referred to them as “Scumbridge”.
That is about the distance between Tranmere and Accrington. How many people would describe that as a derby ? In other parts of the country (London, Yorkshire & Lancashire) how many would call a match a derby between Ipswich and Norwich with a distance of 45 miles ?
East Anglia has so few professional teams that geographically matches between those teams are called derbies.
Yes. When you think back over the past couple of seasons we could have been drawn against a League Two or non league teams but we have ended up with draws against teams in our own league (Coventry, Lincoln and Pompey).
