Arsenal 0-2 West Ham | Preseason champions shocked in season opener [Match report]

Kouyate and Zarate teamed up to earn Westham their first victory over Arsenal since April 2007, in a match that was largely expected to swing the gunners way.

Westham soaked up early pressure albeit at a price, two early yellow cards, just before halftime, debutant Petr Cech misjudged a Payet cross and Kouyate headed home the opener, Emirates stadium was shell shocked and hoped for a response after the break.

Alex Oxlade Chamberlain looked the sharpest player on the pitch early on forcing Mark Noble into the books just five mins on and three mins later Angelo Ogbonna joined him in the referee's book when he clattered into Francis Coqueline.

Westham eased into the game and afterwards stuffing their studs emphatically around the neatly grazed Emirates turf, Aaron Ramsey volleyed an effort in the 33rd minute but his deflected attempt was palmed over by Adrian in the Hammers' goal, the resulting corner was cleared by Sakho and away.

James Tomkins then joined Noble and Ogbonna in the books when he hacked down Monreal in the 37th minutes, that was after Santi's attempt went wide and Olivier Giroud ruled offside though television replay suggests he was level with Ogbonna.

Mesut Ozil then fouled Payet who lofted the resulting free kick into the box for the Hammers' opener. Peter Cech threw himself into the air in an attempt to punch the delicate cross but missed to the delight of the on rushing Kouyate who made no mistakes from six yards out.

The game went into the break with the visitors leading in the sunshine of north London

The derby fans were treated to some end to end stuff early in the second half as the gunners chased the game.

It went from bad to worse in the 57th minute when Oxlade Chamberlain lost possession just outside the Arsenal 18yard box, Mauro Zarate dummies a little and fired down low to beat Cech who was wrong footed by a light deflection.

Slaven Bilic's men are two goals up, all the preseason hopes of Arsenal went up in flames as the hammers ran out 2-0 winners.

Arsenal are not very good at chasing the park, after Chelsea generously dropped points at home to Swansea, it's up to the gunners to put their acts together and concentrate on proper football and less of the selfies...

Welcome to the new season.
