Ronaldo goes in search of a hat-trick but his shot fails to really work Green.

That was a good chance for a consolation goal for the Hammers as they head for their fourth successive defeat.

Di Michele works his way into a great position inside the United box but he dwells on the ball without getting a shot away and eventually runs into trouble

The West Ham substitutes have arguably changed the game for the visitors and Sears has looked good since coming on, much brighter than the ineffectual David Di Michele

The visitors have enjoyed a lot of possession in this second-half but they have failed to make it count - something that will disappoint Zola though Old Trafford is never an easy place to come.

Alex Ferguson will be delighted with the hunger that Rooney has shown since taking the field and the home faithful may also be reassured by Ronaldo's happiness at the club after his first-half brace.

Rooney is looking for his 100th career goal and comes close again with a drilled shot from outside the box forcing a fine save out of Green.

Rooney gets an early shot away as he tries to chip the ball over Green from inside the box but the keeper is equal to the shot.

The Hammers again put together a decent move and again the final product lets them down as Bellamy fires a shot high over Kuszczak's crossbar.

The Champions string together a lovely flowing move but Anderson ends it poorly as he blazes a shot over the crossbar from inside the box.

West Ham enjoy a lengthy spell of possession and try to bombard United with crosses, but all are dealt with by the stubborn United defence.

Worrying signs for West Ham as Wayne Rooney is warming up on the touchline.

Collison goes down in in the box under a challenge from Vidic but the referee waves away the protests.

Bellamy hits an ambitious free-kick from way out and unsurprisingly fails to trouble Kuszczak.

Berbatov shows superb trickery to set up a chance for Nani but his shot sails over the bar and into the stand behind the goal.

West Ham go on the counter with Boa Morte but the attack breaks down as the winger's cross is cleared from danger by Patrice Evra.

A cross picks out Tevez who rises above everyone in the box but Green does brilliantly to pluck the ball off the head of the Argentinian

The home side have taken their foot off the pedal for this second-half but they are showing West Ham no signs of getting back into the game. Zola's side may have to come up with something special if they are going to break down the Champions.

Tevez is bundled over in the box and appeals for a penalty but Peter Walton waves play on.

Ronaldo finds Tevez who brilliantly turns his marker inside out before getting a shot away from the edge of the box but Mullins puts in a vital last ditch block.

Ronaldo cuts inside from the left and gets a shot away but it sails straight down the throat of Green.

Bellamy gets behind the United defence and looks to latch onto a long ball but it is has too much on it and he has to stretch to get in a cross that is dealt with easily by the United defence.

Both West Ham substitutes Boa Morte and Collison have looked lively since coming on but the visitors have still not yet troubled United.

West Ham have changed their system for this second period but we will have to see if the change is effectual.

There is a stop in play for a few minutes as Behrami goes down with an injury - hopefully nothing serious for Zola's side.

The visitors have enjoyed a few spells of possession as the half draws to a close but they have not managed to conjure anything dangerous in the final third.

Zola has a big job on his hands in the dressing room at half-time and will have to do something really special if he is to get his side back into this game.

Anderson tries his luck with a shot from distance but he sends it well wide of the target.

This performance is nothing compared to the West Ham side that came to Old Trafford on the last day of the 07/08 season and caused an upset with a 1-0 win.

Berbatov will get all the credit for that last Ronaldo goal after the Bulgarian chased down a lost cause before showing magical skill on the byline leaving James Collins stunned.

Gianfranco Zola must be furious with his side. They have been woeful so far in this game and are giving the ball away far too cheaply - something you cannot afford to do at Old Trafford.

Faubert cannot cope with Nani but it has to be said that his team-mates have not been much better - they have not yet managed a shot on goal

Nani is sparkling at the moment and looks to be really staking his place for the first team as he terrorizes Faubert yet again down the left flank.

Anderson intercepts a dangerous Lee Bowyer pass across his own goal but he fails to make the most of the opportunity and his shot is hit straight at a grateful Robert Green.

Very promising signs for Alex Ferguson who will be delighted that his side are back to their old ways after they were criticised for a very poor second-half at Goodison Park on Saturday.

Nani leaves Faubert for dead yet again and comes close with a driven shot from the corner of the box.

The Champions have been dominant since the word go at Old Trafford tonight and the goal comes as no surprise. West Ham need to tighten up and get in their faces or they could be in for a long night.

Matthew Etherington tries to get in on the action for the Hammers and runs at goal but his final shot is weak and causes no problems for Tomasz Kuszczak

Julien Faubert gets into a decent position but his cross is dealt with easily by the United defence.

Nani looks sharp in these opening stages and gets another cross into the box but this one flies wildly behind for a goal-kick.

That was a good opportunity for Berbatov and he probably should have put the Champions ahead. West Ham escape this time.

Nani skips past Julien Faubert and pulls the ball back for Dimitar Berbatov in the box, but the striker scoops his shot over the bar.

The home side have started brightly here and look sharp, but no effort on goal so far.
