Liverpool's imperious 68-match, 1,369-day unbeaten home record finally fell after Burnley's 1-0 victory at Anfield.
Jurgen Klopp's side once again paid for their lack of a cutting edge as a fourth league match without a goal cost them dearly.
Here the PA news agency takes a look at the issues facing the defending champions.
What has gone wrong?
Put bluntly, not scoring goals. The Premier League drought now stands at seven hours and 18 minutes. It is their worst run without a league goal since May 2000, when they failed to win their last five matches of the season and did not score for seven hours and 56 minutes. Yet they still finished fourth.
They must be playing badly then?
The problem the Liverpool manager has is he cannot rely on the current back-up to his front three who, bizarrely, have all fallen out of form at the same time. Divock Origi, who has looked like he has been heading for the exit door for 12 months now, has scored two goals – one against League One Lincoln – in his last 26 matches in all competitions. Injury-affected duo Alex Oxlade-Chamberlain and Xherdan Shaqiri have one in 15 and two in 37 respectively. Take away Salah, Mane, Firmino and September signing Diogo Jota and the rest of the squad have contributed just six in the league. With a January transfer unlikely the return of the injured Jota (eight in his last 11 games) cannot come soon enough.
