Philippe Mateta scored twice in the second half as Crystal Palace completed a 2-0 Premier League away win at a toothless West Ham United on Saturday, more evidence for new manager Graham Potter of the difficult job he faces in east London.

Palace's first goal, scored in the 48th minute, was the 10th the Hammers have conceded in the first 15 minutes of the second half in Premier League games this season - more than any other club except Leicester. This was West Ham's 10th league defeat of the season, and they are 10 points above the relegation zone.
