A notoriously strict football coach in Argentina gives his players some unorthodox goalkeeping coaching - joking that Liverpool flop Lauris Karius should have visited him. Diego Svery wanted to be a professional but became a taxi driver after an ankle injury cut short his career in Buenos Aires and started coaching youngsters. He became known for his bizarre training methods - including previous videos of players firing balls over a burning fence which the keeper then has to save. Or hanging the keeper upside down from a crossbar with a hood over his face for him to practice catching the ball blindfolded.
