Alan Pardew's side had marked the takeover of the club with victory over Sheffield United last weekend but with new chairman Eggert Magnusson watching from Goodison Park directors' box, United slumped to a 2-0 away defeat to extend the club's disappointing start to the campaign.

Everton move seventh after weathering early West Ham pressure before taking control of the game through Osman's 52nd minute strike -- his first league goal of the season in his 100th appearance for the club -- before wrapping up the win when substitute Vaughan slotted home in injury time.

But while Everton manager David Moyes was left contemplating a push towards European qualification, opposite number Pardew was left in no doubt about the scale of the task facing him as he attempts to turn his side's season around.

Carlos Tevez retained his place in the West Ham line-up despite his angry reaction to being substituted in last weekend's victory when the Argentinian stormed away from the stadium immediately after being replaced.

Pardew allowed Tevez's punishment to be decided by his team-mates who decreed the forward should be forced to wear a Brazil shirt in training all week and face a fine of 1,000 pounds.

Tevez paid up but refused to be seen in the colours of Argentina's South American rivals and Alan Pardew confirmed the matter was closed by including the forward who responded with a display that should have seen the visitors in control of this game before half-time.

The former Corinthians striker has been slow to adjust to the Premiership but he was a constant threat to the home side in a one-sided first half, drawing a fine save from Everton keeper Tim Howard and setting up Lee Bowyer with a glorious chance to open the scoring in the 18th minute.

Gliding easily past the challenge of Joleon Lescott, Tevez pulled the ball back to Bowyer who stared in disbelief as Howard reacted superbly to turn the midfielder's first time shot over the bar.

West Ham's superiority was confirmed by their haul of ten corners inside the first half hour but Everton finally began to make an impression through Andy van der Meyde and Andy Johnson who had both been hurriedly brought into the line-up after training ground injuries to Phil Neville and Mikel Arteta a day earlier.

Van der Meyde has endured a miserable time since his 1.8 million pounds transfer from Inter Milan in summer 2005 but he marked his first Premiership start of the season with a series of quality crosses deserved more reward.

Relieved at having reached half-time on level terms, Everton finally began to take control of the game and West Ham were forced to rue their earlier missed opportunities when the home side went ahead in the 52nd minute.

Striker James Beattie created the chance by chasing down a long ball that appeared to be going out and delivering a threatening cross that Jonathan Spector could only half-clear towards Osman on the edge of the box.

The youngster showed impressive composure to bring the ball down on his chest before volleying past Green before Vaughan ended west ham hopes in the final seconds.
