Tottenham forward Son Heung-min had to be dragged onto his feet as Antonio Conte lead his squad through a pre-season training session in Seoul.
Conte is known for his gruelling drills with the aim of making his players tougher than the rest - to make their rivals "spit blood" - and the 6,000 fans watching Spurs' open training session at Seoul World Cup Stadium on Monday could see that in action.
The likes of Son and Harry Kane were forced to take a breather as the squad were sent on repeated sprints across the length of the pitch and back after a two-hour training session.
New signing Yves Bissouma was another whose legs gave way after another shuttle run, while Lucas Moura had to use the advertising board to keep upright.
Away from the main group, fellow summer arrival Ivan Perisic took part in some individual work as he continues to work back from injury.
Striker Troy Parrott, back with Spurs after a successful loan spell at MK Dons, appeared to be the fittest on show and lasted the entire drill.
Spurs face K-League XI on Wednesday and Sevilla on Saturday.
