Crystal Palace 1-0 West Ham: Sam Allardyce 'frustrated and angry'

Manager Sam Allardyce is "frustrated and angry" as West Ham "gift" Crystal Palace the only goal in a 1-0 win.

Joey O'Brien "made a mistake" in allowing Marouane Chamakh space to head in the winner and Stewart Downing had a goal disallowed when "the officials got it wrong".

The Hammers' third defeat in their last four Premier League games leaves them 15th in the table, only three points above the relegation zone.
