In 2002, former Liverpool Reserve player Jimmy Rolfe loaned to Anfield Museum a No. 11 shirt believed to be the only surviving example worn by Liddell in the league. He had acquired it from trainer Albert Shelley on leaving for Chester in 1953. On 4 November 2004, widow Phyllis and Ian Callaghan unveiled a commemorative plaque adjacent to the museum. Liddell's biographer John Keith, who also presented on BBC Radio Merseyside, had proposed the memorial to then chairman David Moores and chief executive Rick Parry. Further recognition came in 2006 when Liddell attained sixth place in a poll of more than 110,000 people conducted by Liverpool's official website to determine a list of "100 Players Who Shook The Kop". When Liverpool approached former players to identify their personal favourites as a complement to the list, Ian Callaghan, Tommy Smith, David Johnson, and Roy Evans included Liddell in their "top five". The Football League included Liddell in a 1998 list of notable players, titled the "100 Legends".
