West Ham United boss Sam Allardyce felt Wayne Rooney's wonder goal in Manchester United's 2-0 win should never have stood.
Allardyce lamented what he saw as a "blatant foul" on defender James Tomkins in the build-up to Rooney's spectacular goal.
Rooney's cheeky nudge in Tomkins' back created the space for his lob.
"It was such a wonderful goal from Wayne Rooney early on but it was a bit of a sickener because I thought it was a blatant foul on James Tomkins," said Allardyce.
"He was easily going to head the ball away. Wayne Rooney took him off his balance when he jumped so he missed the header.
"So technically the referee has made a big error because the opposition have scored from that error."
