The 1920âÂÂ21 season was the 46th season of competitive football in England.
The Football League Third Division is introduced, expanding the League's operational radius south of Birmingham by absorbing top division of the 'non-League' Southern Football League into its ranks. Cardiff City, however, as the strongest club in Wales in the era, is invited directly into the Second Division, and Grimsby Town takes its place in the new Third Division, thereby being the first club relegated to the League's third tier. Leeds United is also elected into the Second Division to replace Leeds City after its debacle. Lincoln City is not re-elected to the Second Division and thus Port Vale's Second Division place is formalized as well.
