What happened: Lincoln packed Sincil Bank with 7,598 others for a 4-1 home win over Manchester City in the League Cup on this date 30 years ago. The tie stayed tilted the following week when John Beck's team won again at Maine Road.

Why it matters: That made it a two-leg result over Manchester City rather than a one-night cup shock. For Lincoln City, the return-leg win gave the scoreline more staying power than a single upset would have carried on its own.

What to watch: Any fresh archival detail from Sincil Bank or the return leg would add the next layer to a result that still travels well three decades later.
