Premier League: Swansea City 3 West Ham 0

West Ham were the architects of their own downfall on Saturday as two defensive mistakes contributed to a 3-0 loss at Swansea City.

First goalkeeper Jussi Jaaskelainen allowed Angel Rangel’s attempted drive across goal to slide underneath his body and into the net on 20 minutes, before Michu was able to pounce on James Collins’ weak backpass to slide in and score the Swans’ second nine minutes later.

Danny Graham added a third just after the hour mark to round off a thoroughly convincing win for Swansea.

Swansea were jittery in the opening stages, seemingly finding it difficult to get into the rhythm of the game.

West Ham could have taken the advantage after 90 seconds, but debutant Matt Jarvis’ cross flew just inches over the head of Kevin Nolan.

The scare woke the hosts up and they were soon at their fluid best, causing Sam Allardyce’s charges havoc down the wings, with Rangel particularly impressive with marauding forward runs.

And it was the right-back’s adventurous nature that handed Swansea the lead after he delayed his retreat back to defence to allow Jonathan de Guzman to find him just inside the area.

A quick dart forward was followed by a low drive by Rangel which Jaaskelainen really should have prevented from bouncing up and into the net.

And that howler was a sign of things to come for the Hammers as Collins, under minimal pressure, managed to fluff a backpass to his keeper and allow Swansea striker Michu to nip in and coolly score his third goal in two games.

West Ham were struggling to assert any sort of pressure on the Welsh outfit, with many aimless balls being pumped forward in the vague direction of lone frontman Carlton Cole.

Jarvis, however, continued to shine on his debut.

He combined well with Nolan to power a half-volley towards Michel Vorm’s goal that was blocked by Chico, before the new-boy turned provider for Cole, only to see the striker’s header cleared off the line by Neil Taylor.

Swansea were in cruise control after the break and Graham went close to scoring when he was played in by Leon Britton, but he bent his shot the wrong side of the post with only Jaaskelainen to beat.

He did not have to wait too much longer for a goal, however, when Collins was again exposed at the back by De Guzman’s clever ball into the box towards Wayne Routledge. The winger turned quickly and dinked a smart cross towards the far post for the striker to sweep home.

The remainder of the game was played out with relative ease, despite West Ham’s vain attempts to spark a revival, with a special moment of note for Swansea youngster Ben Davies, who was handed his senior debut by Laudrup with just over five minutes remaining.
