Derby County F.C.
The Football League began again the next season, but Derby did not play well and were relegated in 1953. Things went from bad to worse and in 1955 they were relegated to the Football League Third Division (North) for the first time in their history.  Derby were too good for that league though, and finished second at the first try.  Then they did even better next season by finishing first, and going back up to the top division.
