Jurgen Klopp hailed Liverpool's resolve to overcome the difficulties posed by going for an unprecedented quadruple as a much-changed team beat Newcastle 1-0 to edge ahead of Manchester City at the top of the Premier League. Naby Keita scored the solitary goal at St. James' Park to take the Reds two points clear of City, who can retake top spot when they travel to Leeds later on Saturday. With the game sandwiched between two legs of a Champions League semi-final against Spanish side Villarreal, Klopp made five changes, including resting key players Mohamed Salah, Thiago Alcantara, Fabinho and Trent Alexander-Arnold.
