Liddell gained two additional caps representing a Great Britain XI against the Rest of Europe in 1947 and 1955. He became one of only two players (the other being Stanley Matthews) to twice be selected. The first exhibition had been arranged to celebrate FIFA's readmission of the four Home Nations. Promoted as the "Match of the Century" and watched by 135,000 spectators, the game ended in an emphatic 6–1 victory for Britain. Liddell sustained a pulled muscle, which severely impaired his movement on the pitch and forced him out of two domestic matches. In the second match, organised to observe the 75th anniversary of the Irish FA's creation, the Rest of Europe won decisively by a scoreline of 4–1.
