John Clark, who has died aged 84, was a member of the Celtic team that won the European Cup in 1967, the first time the trophy was secured by a British club. Playing alongside the imperious centre-half Billy McNeill, Clark was the ultra-efficient sweeper at the heart of defence.
Clark and McNeill always shared a room, and a snap taken on the morning after the triumph in Lisbon showed the two men, both from working-class backgrounds in Lanarkshire, sleeping contentedly with the greatest prize in world club football perched between their beds.
