Scunthorpe United
Born in Skegness, Lincolnshire, Clemence played eight matches on trial for Notts County, but was ultimately not signed by the Meadow Lane club. He was spotted by Scunthorpe United whilst playing in a county-cup final at their Old Showground ground for his local youth club Skegness Cosmos. After starring in the Cosmos' 4-3 victory, Clemence was invited for formal trials with The Iron, which he duly passed. Clemence went on to sign professional terms for Scunthorpe on his 17th birthday, 5 August 1965, shortly before the start of Scunthorpe's 1965–66 Third Division campaign.
Despite initially playing in the club's 'third team', Clemence's big break arrived later in his debut season – making his professional debut in a 1–1 draw at home to Swansea Town on 2 April 1966. Prior to this debut, Clemence remembers a key behind-the-scenes intervention from two Scunthorpe coaches: "Jack Brownsword and Alan Bushby pulled me aside, gave me a pep talk and told me they thought I could play for England one day but 'you've got to work at it'".
Clemence went on to make four appearances in total throughout his debut season, including earning his first professional clean sheet in a 1–0 victory away at Southend United. Having spent much of that season as understudy to the experienced former Wolverhampton Wanderers and Aston Villa custodian Geoff Sidebottom, Clemence later cited Sidebottom as a crucial early mentor: "I learned a lot from Geoff. He taught me how to look after myself because 'keepers were a lot less protected then."
During his time at the club, Clemence lived with Mrs Ruby Duce of King Edward Street in Scunthorpe; in the very same digs which would then immediately be occupied by his future England and Liverpool teammate Kevin Keegan following Clemence's departure to Liverpool.
After being reintroduced to the side after they had lost their opening three games in all competitions, Clemence became Scunthorpe's undisputed first-choice goalkeeper in their following 1966–67 Third Division campaign, in which they finished a disappointing 18th. After manager and ex-Busby Babe Freddie Goodwin departed mid-season for the New York Generals in the nascent North American Soccer League, Clemence spent the latter half of his season under the guidance of caretaker player-manager Keith Burkinshaw, who would later also sign the player for Tottenham Hotspur.
And despite Clemence himself worrying that a humiliating 7–1 defeat away to arch-rivals Grimsby Town could end his professional career, Scunthorpe's faith in him never waivered and this defeat proved to be the second game in a run of 46 consecutive starts he made to see out all of Scunthorpe's remaining league and cup matches.
This run took Clemence's figures to 50 appearances and 12 clean sheets in all competitions for Scunthorpe; but unbeknownst to him, he had been scouted in 12 games by legendary Liverpool manager Bill Shankly and his coaching staff. This came to fruition later that summer, when Clemence was forced to leave a beachside deckchair-stacking shift early, with the news that an urgent telegram awaited him at home. This was because Liverpool's bid for the now 18-year-old shot-stopper had been accepted, and the Scunthorpe chairman personally drove Clemence to Anfield in his Rolls-Royce the next morning.
Looking back on his time with the club, Clemence fondly recalled how Scunthorpe United was: "A club I'm proud to be associated with. While I was there, it was like being part of a family.
