Liverpool lost ground on leaders Arsenal after slipping to a 3-1 defeat to Hull City.
Steven Gerrard cancelled out an early strike from Jake Livermore, but second-half goals from David Meyler and Tom Huddlestone earned the Tigers the three points.
Livermore gave Hull the lead on 20 minutes, but Liverpool fingers will be pointed the way of Victor Moses.
The Chelsea loanee gave the ball away in sloppy fashion deep in his own half and was made to pay a heavy price as Livermore’s shot deflected off Martin Skrtel and beyond Simon Mignolet.
Gerrard came to Liverpool’s aid with a leveller on 27 minutes. The England captain lined up a free-kick and as Hull keeper Allan McGregor took one step to his right, Gerrard fired the ball round the wall and into the far corner.
With no Daniel Sturridge on account of injury, Luis Suarez had to plough a lone furrow in attack, and he looked exposed at times.
McGregor might have been a shade culpable for Gerrard’s equaliser, but he kept his side on level terms with a brilliant save to deny Moses from point-blank range.
It proved a vital save, as less than a minute later Hull edged themselves in front.
A loose ball fell to Meyler, and he arrowed a shot across Mignolet and into the bottom corner.
Liverpool failed to fashion a response, and they were hit on the break as Huddlestone’s shot took a wicked deflection off Skrtel and into the net.

The win, Hull's first victory over Liverpool in any competition, puts breathing space between the Tigers and the drop zone. For Liverpool, they are now seven points behind Arsenal.
Steven Gerrard: C
It was 15 years on Friday that Gerrard made his debut for the Reds.
He has driven the side on for that period, and it was no different on Sunday. It wasn’t the best day for the Reds, but their captain got himself a goal.
Luis Suarez: D
A rare off day for the Uruguayan, who was starved of service. When he did receive the ball, he either ran into defenders or down blind alleys.
Following the defeat, Reds boss Brendan Rodgers spoke to the club’s official website and admitted they are now facing a test of their resolve.
This little period now will test us. We've got players that will come in and it's a great opportunity for them to stake a claim for a place in the team.
Hopefully we get back to winning games on Wednesday [versus Norwich].
