This big goalkeeper joined Liverpool from Watford in December 1953 and was one of three different stoppers used in league matches during the 1953-54 season - the others being Charlie Ashcroft and Russell Crossley.
Liverpool had been shipping goals and were heading for the Second Division. Underwood went straight into the side after his arrival from Vicarage Road and only missed two games between his debut on 19th December 1953 and the end of that season.
Underwood started the following season as first choice, but lost his place to Ashcroft after only a handful of matches and didn't get another first-team opportunity until at the end of November 1955.
He took over from Doug Rudham but the South African won his place back before the end of the season and Underwood returned to Watford in July 1956.
Underwood had three spells at Watford (1952-3, 1956-7 and 1960-63) and was a very popular figure at the club.
In 1977 Underwood was the chairman of Barnet from the 1977-78 season to 1981-82. In his tenure at the club Barnet signed footballing great Jimmy Greaves, who later thanked Underwood for helping him in the fight to overcome his much-publicized personal difficulties.
