Liverpool manager Juergen Klopp sounded as surprised as everyone watching as he tried to explain two dreadful errors by Brazilian keeper Alisson that helped Manchester City to a crushing 4-1 win at Anfield on Sunday.

Alisson, so often Liverpool’s saviour in the past two seasons, gifted possession to City players twice in the space of three second-half minutes with errant passes and was punished both times as Ilkay Gundogan gave City a 2-1 lead and Raheem Sterling added another.
