Six of the best: Manchester United

Old Trafford has for years been regarded as a fortress for Manchester United under the guidance of previous manager Sir Alex Ferguson.

Now, after two consecutive home defeats in the Barclays Premier League, the Theatre of Dreams perhaps doesn't now seem so daunting.

The Hammers will be hoping to follow in the footsteps of West Bromwich Albion, Everton and Newcastle who've all emerged victorious from trips to Old Trafford this season.

Here, takes a look at six memorable away wins for West Ham against Saturday's opponents.

West Ham travelled to newly-crowned Champions Manchester United on the final day of the 2006/07 season needing a point to be sure of their Premier League status.

As it was, the Hammers took all three points thanks to controversial Argentinean Carlos Tevez who scored on the stroke of half-time, placing his shot past Edwin Van der Sar after exchanging passes with Bobby Zamora.

The visitors were able to hold out in the second half as they ensured top-flight football would be played at the Boleyn Ground for another season.

West Ham inflicted a third straight league defeat on the Red Devils as a single goal from Jermain Defoe was enough to earn them all three points.

The defining moment came with 64 minutes on the clock as the diminutive striker headed home unchallenged at the far post following excellent work by Paolo Di Canio.

Visiting keeper David James then made a string of fine saves to keep his side in front and earn himself a precious clean sheet.

A game famous for the antics of United's eccentric French goalkeeper, Fabian Barthez, saw the Hammers through to the fifth round of the FA Cup.

76 minutes had elapsed when Paolo Di Canio bore down on goal with Barthez stood, one hand aloft, appealing in vain for an offside decision which never came.

The Italian proceeded to slot the ball past the Frenchman, leaving the Red Devils and their bemused fans out of the FA Cup.

By the end of the season the Hammers had managed to stabilise and finished the campaign in 17th place.
