Newcastle manager Alan Pardew has renewed calls for goal-line technology after sympathising with Everton counterpart David Moyes following his side's two disallowed goals.
Second-half Magpies substitute Demba Ba had cancelled out Leighton Baines' opener before Marouane Fellaini had an effort wrongly chalked off for offside in Monday night's 2-2 draw at Goodison Park.
The Toffees were then left more aggrieved when Victor Anichebe's header was not allowed to count despite appearing to cross the line.
"My analyst said to me it was over the line," said Pardew.
"These decisions are game-changers, there is no doubt about it and I am sure David will be very aggrieved.
"I have been saying all along that technology must come in and it has cost Everton a crucial goal."
Moyes hoped the officials would recognise they had made mistakes but admitted that would be no consolation.
"There are two goals missed so I can't get them back but you hope that the linesman has a look and sees how he missed them," said the Scot, who spoke to the officials after the game.
"I had a word and said 'You've missed two goals' and it does affect the outcome of the game, but what can I do about it?
"I am sure the referee will have a look at them himself and see if he got it right or wrong - which we all know because we have seen it.
"Fellaini's goal was onside and if your job is to look along the line you hope the linesman sees if the ball crosses the line, but we've seen many occasions where they don't get it right.
"I thought the offside goal was a goal from the touchline so I was surprised when it was ruled out.
"The other one you can't really tell but the reaction of the players was that they felt it was over and they are not usually far off the mark."
