I've never bothered to look up about Ipswich's top division victory and UEFA Cup win, but this thread prompted me to do so.
I hadn't realised that Ipswich won the league immediately after promotion, for example, or indeed in their first season in the top flight. Burnley, of course, were their main competitors.
In the 1981 UEFA Cup run, Ipswich qualified by virtue of being third in the top division. You can only play what's in front of you, but their opponents being Aris Saloniki, Saint-Etienne, FC Koln and then AZ '67 (now Alkmaar) represented a very comfortable set of opponents, even then. As well as being fewer rounds than later competitions. Saint-Etienne were probably the toughest of that lot.
Interestingly, those were the days with two-leg finals, and Ipswich's 3-0 home win was enough to see them through despite a 4-2 defeat away.
Different times, then, though Ipswich's wins were undoubtedly impressive. The league win must go down as one of the most extraordinary. We're massively helped by our UEFA run being (a) in more recent memory and (b) being the very English fairy tale of the underdog taking on the massive favourite in spirit and style. Plus helped by an astonishing Goss goal. I do think, though, East Anglia on the whole have massively underperformed, particularly domestically. Just three cup wins between us and a half-century old league title is just not good enough, even for a region that's something of a backwater.
