London, March 17:

West Bromwich Albion were left four points adrift at the bottom of the Premier League after an uninspiring goalless draw away to West Ham at Upton Park on Monday.

The visitors had the best chances of the match. Shelton Martis hit the bar while ex-Manchester United midfielder Jonathan Greening shot over the top from six yards out and James Morrison saw his effort saved by West Ham keeper Robert Green.

West Ham, who remained seventh in the table, rarely threatened to score against Tony

Mowbray’s basement club. Mowbray said that there had been no difference in their level of performance from recent matches. “I don’t think it was an improved performance — the defence was better but the performance was what we get most weeks.”

There was a worrying moment for the already injury-hit Hammers when centre-back Matthew Upson went off in the first-half with a leg problem. But the good news for manager Gianfranco Zola was that Upson was later seen walking freely after being carried off on a stretcher.
