West Ham 3-1 Liverpool: Third Premier League defeat in four matches for the Reds.

Goals from Winston Reid, Diafra Sakho and Morgan Amalfitano boost the Hammers as Brendan Rodgers' side slump to another loss seven days after Aston Villa triumphed at Anfield.

Liverpool went down 3-1 to West Ham at Upton Park to make it three defeats from their last four Premier League matches.

Winston Reid and Diafra Sakho capitalised on some poor defending to give the hosts a surprise lead just seven minutes in to Saturday's game at Upton Park.

And, although Raheem Sterling provided hope for the visitors with a 26th-minute screamer, West Ham defended admirably to secure all three points, with substitute Morgan Amalfitano making the game safe late on.

The Frenchman guided the ball into the far corner with two minutes left to score his first goal since joining West Ham from Marseille in the summer.

By Liam Twomey One suspects Brendan Rodgers didn't lose too much sleep last night worrying whether Stewart Downing would come back to haunt him, but the one-time Liverpool cast-off was instrumental in this victory. Operating in the same No.10 position which saw him impress against Hull City he pulled all the strings as West Ham put the match beyond Liverpool in the opening 10 minutes. The early blitz was a trick often employed by Rodgers' title-challenging Reds last season but here they were undone by familiar weaknesses: slack set-piece marking and poor defensive positioning. Despite significant investment they are on course to beat the total of 50 goals conceded which ultimately cost them the Premier League last year. Sam Allardyce, however, will breathe a little easier. Results at home have intensified the pressure from a West Ham support one senses will never warm to his presence in the dug-out. But if this performance is a sign of things to come, they may feel compelled to.

The result marked the Londoners' first home Premier League win of the campaign, while Liverpool's early title ambitions were once again exposed following their defeat at home to Aston Villa on their last Premier League outing.

West Ham boss Sam Allardyce made just one change from the side that drew 2-2 with Hull, handing a full debut to former Barcelona midfielder Alex Song in the centre of midfield.

Liverpool boss Brendan Rodgers, meanwhile, made three alterations from the midweek Uefa Champions League win over Ludogorets, with Martin Skrtel, Lucas Leiva and Fabio Borini all coming in.

Rodgers once again named three close-season signings in the shape of Alberto Moreno, Dejan Lovren and Javier Manquillo at the back, but that trio could not prevent the visitors from making a shambolic start in defence.

With just two minutes gone, a West Ham set-piece caused chaos in the area and allowed James Tomkins to nod the ball back into the middle, where Reid was on hand unmarked to bundle home.

It went from bad to worse for Liverpool a few moments later, as Sakho's chipped cross-cum-shot from the right found the far corner of the net, with goalkeeper Simon Mignolet flailing.

Rodgers had clearly seen enough and soon withdrew Manquillo for Mamadou Sakho in order to switch to a 3-5-2 formation more suited to negating West Ham's threat in the air.

But it was at the other end of the pitch where Liverpool were given brief hope of a turnaround.

Mario Balotelli produced a fine piece of control in the box after 26 minutes before his shot was blocked, but Sterling was on hand to smash home the rebound from the edge of the area.

West Ham continued to threaten despite that goal and soon caused more disarray in the Liverpool defence that led to Lovren and Sakho clashing heads in the air.

The Croatian appeared to come off worse but he managed to continue after a spell of treatment.

Perhaps unsurprisingly, Liverpool made a further change after hanging on until the break as Adam Lallana replaced the ineffective Lucas.

And the £25 million man's introduction almost paid immediate dividends as he set up Sterling for a shot from the edge of the box, but it trickled wide.

Lallana proved to be a catalyst for an improvement in Liverpool's previously ragged attacking play, although West Ham remained a real threat on the counter-attack.

The England international set up Borini to drive a shot just wide before, at the other end, the hosts broke at pace and Sakho chipped onto the roof of the net.

Rodgers threw on Rickie Lambert 15 minutes from time in an attempt to find an equaliser, but West Ham killed the game off when Amalfitano toe-poked home at the end of a flowing move.

The defeat leaves Liverpool 10th in the Premier League table, six points behind leaders Chelsea having played a game more. West Ham also leapfrogged the Reds into eighth, with seven points.
