Livepool spent over $200 million on players in the summer transfer window.
Liverpool signaled its determination to challenge for the title by spending more than $200 million on players, more than any other Premier League team in the summer transfer window.
With debuts for Alisson in goal and Naby Keita in midfield, Liverpool opened with a 4-0 victory over West Ham.
Mohamed Salah, who scored 44 times in his first season at Liverpool, took only 19 minutes to get off the mark at Anfield by meeting Andrew Robertson's cross with a tap-in.
Another cross from Robertson opened up West Ham for Liverpool's second in first-half stoppage time. James Milner's cutback was turned into the net by Sadio Mane, who added a third eight minutes after the break.
Even after Salah was taken off, the Egyptian's replacement, Daniel Sturridge, found the net late.
Liverpool, which finished fourth last season, hasn't won the English title since 1990.
''We know about our expectations and we realize there is a really positive atmosphere around us in the pre-season,'' manager Juergen Klopp said. ''That is good that people are positive, but this season will be unbelievably hard. We cannot be anything different than the challenger because we haven't won anything since I came in.''
Also Sunday, Southampton and Burnley drew 0-0.
