Nuno Espirito Santo became the first Premier League manager to admit he is ignoring heading-limit guidelines in training, prompting concern from dementia campaigners.
Football’s authorities advised clubs at the start of this season that their players should not be exceeding 10 high-force headers a week in light of a growing link to neurodegenerative diseases.
Sources have told Sportsmail that the Tottenham boss is not alone in disregarding guidance. An executive at another English club said: ‘We just have to be seen to be doing something.’
Speaking ahead of Sunday's north London derby against Arsenal, Nuno had said Tottenham need to improve at defending set-pieces.
