West Ham United boss Sam Allardyce was delighted with Matt Jarvis' performance in defeat to Chelsea.

Allardyce was disappointed his strikers failed to make more of the winger's service.

"He was our biggest threat today, every time we got him the ball today he skinned the full back. He put the ball where he should do, in the right areas with the right quality, but again the old Achilles heel for us of not scoring away from home has risen again," said Allardyce.
