Jurgen Klopp celebrated his first win at Old Trafford as Liverpool came from behind to beat Manchester United and boost their chances of a Champions League place.
In a thrilling game played against the backdrop of noisy protests against the United ownership outside the ground, United struck first through Bruno Fernandes' deflected opener.
But Liverpool, who had seen one of their buses prevented from picking team members up before the game after being blocked in the street, hit back through Diogo Jota's instinctive effort.
Roberto Firmino, who had only scored once since his two-goal haul at Crystal Palace in December, then put his side on top with a well-taken double either side of half-time.
