Following the 191415 edition, the competition was suspended due to the First World War, and didn't resume until 191920. The 192223 competition saw the first final to be played in the newly opened Wembley Stadium (known at the time as the Empire Stadium). Due to the outbreak of World War II, the competition wasn't played between the 193839 and 194546 editions. Due to the wartime breaks, the competition didn't celebrate its centenary year until 198081; fittingly the final featured a goal by Ricky Villa which was later voted the greatest goal ever scored at Wembley Stadium, but has since been replaced by Steven Gerrard.
Is there an answer to this question (If it cannot be answered, say "unanswerable"): Why was the Empire Stadium renamed to Wembly Stadium?
