The centre-back missed out against the Hornets on Saturday, but will one man have changed the result at Vicarage Road and prevented the Reds' wobble?
When you’ve gone 44 games unbeaten in the Premier League, won a record-equalling 18 games in a row, and are now a win away from holding the record for wins in the history of the competition, any defeat will obviously lead to some sort of post-mortem.
That’s what Liverpool have endured since Saturday’s heavy 3-0 defeat by Watford, the second-bottom team before a ball was kicked, a side who were winless in five before the weekend’s clash at Vicarage Road.
