Graeme Souness is one of the toughest footballers of all time, a midfield titan for Liverpool and Scotland in the 1970s and 1980s. He was occasionally outwitted by subtler players such as the Brazilian genius Zico, but no opponent ever got the better of him physically.
No human opponent, anyway. During the 1986 World Cup in Mexico, Souness lost a stone in weight (6.35kg) against West Germany at Querétaro in stifling heat and at high altitude. “I can remember going down on my haunches and thinking: ‘God, do I not feel good,’” he said. “It was the worst I ever felt on a football pitch. I couldn’t breathe.”
