Leeds United and Aston Villa produced one of the most unbelievable moments in football history during their 2019 Championship clash. After Leeds scored while a Villa player was down injured, chaos erupted on the pitch, leading Marcelo Bielsa to famously instruct his team to allow Villa to walk in an uncontested equaliser. The match ended 1-1, but the incident became iconic for its controversy, sportsmanship and unforgettable scenes.
