Jurgen Klopp’s side dominated this first European meeting between the two Premier League giants in a thunderous atmosphere – and the German manager’s only disappointment will be that the tie is not already settled.
Daniel Sturridge gave Liverpool a 15th-minute lead from the spot after Memphis Depay fouled Nathaniel Clyne and Roberto Firmino added a second from close range with 17 minutes left.
United did not create a single chance and only the brilliance of goalkeeper David de Gea has kept Liverpool in range as he produced a succession of magnificent saves.
