Liverpool captain Steven Gerrard has urged referees to step up after a linesman wrongly flagged Luis Suarez's winning goal against Everton offside.
The Uruguayan international found the back of the net in the dying seconds of the Merseyside derby yesterday but it was swiftly ruled out, despite replays showing that the frontman was onside.
"I've seen it again and we can feel sorry ourselves because it was a clear goal," Gerrard told the Liverpool Echo. "We should be taking away the three points rather than just one. There is no offside and it's difficult for me to explain it. The only person who can explain it is the linesman.
"I asked him after the game if it was offside and he said 'I think so'. That's not good enough. If every decision in this league is based on 'we think so' then we're in trouble.
"The linesman got it badly wrong. The benefit of the doubt is supposed to go to the attacking player anyway."
The explosive clash finished 2-2 between the rivals.
