Crystal Palace secured a fifth consecutive away win as Alan Pardew enjoyed a 3-1 Premier League victory over former club West Ham.
Alan Pardew enjoyed his latest return to Upton Park as Crystal Palace made it five away wins in a row with a 3-1 Premier League victory against West Ham.
Palace has won all five of its matches on the road since Pardew took the helm, with Saturday's triumph - completed with 10 men on the field as Glenn Murray was dismissed - giving his charges a comfortable advantage over the bottom three.
When Pardew took Newcastle United to West Ham back in October, Aaron Cresswell's goal proved decisive - but the defender had a very different impact this time around.
In attempting to clear a tame Murray header from Jason Puncheon's corner, Cresswell succeeded only in sending the ball spinning into his own net on the stroke of halftime.
Sam Allardyce may lament the fact that the striker - one of four Palace changes - had five minutes earlier escaped a possible red card when, having already been booked, he clumsily fouled Cheikhou Kouyate.
Allardyce's mood will have darkened significantly just six minutes into the second half when his side failed to defend another Puncheon corner, with Scott Dann profiting to head home from close range.
The contest was over in the 63nd minute when Murray steered a diving header past Adrian, with Puncheon again the provider, though the Palace striker did eventually get his marching orders for a foul on Winston Reid.
Enner Valencia reduced the deficit with a superb late strike, but Palace exacted revenge for August's 3-1 home loss against West Ham.
It was the hosts who threatened first, with Mark Noble's 14th-minute free kick casting Julian Speroni in the role of mere bystander — but striking the crossbar.
Palace's first clear sight of goal came midway through the half as Murray - one of four changes for the visitors - collected Puncheon's pass before slicing his shot wide of the target.
The same duo linked up again on the half-hour mark as Adrian was called into action to block with his legs, before Jordon Mutch was forced off injured to be replaced by the returning James McArthur.
Having survived one scare in the box when Damien Delaney volleyed an effort into the ground that looped across the 6-yard box, West Ham was punished on the stroke of halftime.
Cresswell stuck out a boot to deal with Murray's header, but the ball skewed into the net as the Palace forward took full advantage of his initial let-off from referee Mike Dean.
Things went from bad to worse for Allardyce early in the second half as Puncheon's corner was headed in by the unchallenged Dann, while Murray's header was followed six minutes later by his dismissal.
Valencia's 20-yard strike allowed West Ham a strong finish but, after Carl Jenkinson and the Ecuadorian were denied late, the hosts saw their winless run extended to six games.
