Their record stands at four wins from four and Liverpool remain, for now at least, at the top of the Premier League although this was a much more rigorous examination of Jurgen Klopp's team's title ambitions than those that have gone before it.

Liverpool overcame a terrible mistake by Alisson to beat Leicester City 2-1 on Saturday and maintain their perfect start to the Premier League season.
The visitors led thanks to Sadio Mane's well-taken 10th-minute strike - the Senegalese's fourth league goal of the season - before Roberto Firmino's downward header doubled their advantage on the stroke of half-time.
However, Rachid Ghezzal - on his first start for the Foxes - took advantage of an awful error by Alisson, who got caught in possession, to give the hosts hope just past the hour-mark.
Liverpool stay top of the table having won their first four league matches for the first time since 1990, while Claude Puel's men remain on six points after a second defeat of the campaign.
