WEST Ham United put in their best performance since moving to the London Stadium as they swept a lethargic Manchester United aside on Saturday.

The Hammers grabbed their first Premier League win at home this season thanks to a 3-1 triumph.

And although United boss Jose Mourinho blamed the officials for his side coming away with another defeat, his tactics played into West Ham’s hands.

When the visitors’ team was announced with midfielder Scott McTominay playing in defence alongside Victor Lindelof and Chris Smalling, Marko Arnautovic must have been overjoyed.

The trio were unable to deal with the pace, power and strength of the Austrian, who marked his return to the team with the third goal to kill the game off.

West Ham went into the encounter without a home Premier League win, so it came as a huge surprise to find Mourinho was playing with five at the back.

A Manchester United led by Sir Alex Ferguson would never have travelled to West Ham - or a team still finding their feet under a new manager - with such defensive tactics.

The pace and trickery of Felipe Anderson, who put in his best performance since becoming the club’s record signing in the summer, was too much for Ashley Young to handle and Anderson was fully deserving of his wonderfully taken first goal in English football.

Andriy Yarmolenko also had the beating of Luke Shaw on the opposite flank and so it resulted in United’s wing-backs being nullified.

The trio of Mark Noble, Declan Rice and Pedro Obiang won the midfield battle against Nemanja Matic, Marouane Fellaini and World Cup winner Paul Pogba, while defenders Issa Diop and Fabian Balbuena gave Romelu Lukaku scraps to feed off.

West Ham were dominant, played terrific football and will now look to build. Manuel Pellegrini’s changes are now coming to fruition.
