1930–31 Birmingham F.C. season

[1] Birmingham "won finely" at Anfield to defeat Liverpool 2–0,[3] then eliminated Port Vale and, with Ernie Curtis "in magnificent form", Watford,[4] to reach the sixth round in which they played Chelsea.

[5] The replay at Stamford Bridge, before a ground-record crowd of 74,365 with thousands more locked out, remained goalless until Chelsea half-backs John Townrow and Sid Bishop were injured.

Sunderland's players thought they should have had a penalty, they failed to take numerous chances, and Harry Hibbs made some fine saves, but three minutes from time, Curtis had a shot blocked, Bradford "rushed in to help his colleague and between them they scored the second goal".

[7] After six minutes of the final, Bob Gregg's header from Jimmy Cringan's free kick was ruled offside; newspaper reports suggest the decision was incorrect.

But straight from the restart, Albion ran the ball down the field, George Liddell sliced his clearance to Richardson's feet, and the forward scored from close range.
