Aston Villa boss Steven Gerrard says they deserved victory after Saturday's 1-1 draw against Manchester City.
Villa thought they had scored a winner when Philippe Coutinho put the ball in the net off the underside of the bar.
However, the assistant referee had already put his flag up for offside - even though Coutinho was actually onside - and some of the City players stopped before the ball went into the net.
Gerrard revealed he had spoken to the officials about the decision after the match, and they admitted they had made an error.
"I've spoken to the officials calmly, and given them enough time after and asked for their side of it," said Gerrard.
"The referee blew the whistle too soon. When something is so tight it's worth an extra bit of time and we could've scored a second goal.
"Fair play to the officials, they recognised that afterwards. It was nowhere near offside."
