Newcastle manager Alan Pardew sympathised with counterpart David Moyes after Everton had two goals disallowed in last night's 2-2 draw.
Second-half substitute Demba Ba had cancelled out Leighton Baines' opener before Marouane Fellaini had an effort wrongly chalked off for offside and 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."
Prior to the match there was a moving tribute to the victims of the Hillsborough disaster after the publication of the independent panel's report which revealed the truth about the tragedy.
Two mascots wore an Everton number nine shirt and a Liverpool shirt with the number 6, ball boys' tops bore the number 96, while the names of all victims of the disaster scrolled across Goodison's television screen accompanied by The Hollies' He Ain't Heavy...He's My Brother.
"I think Everton, when the disaster happened, stood alongside Liverpool because there are families in the city with mixed support for both clubs," said Moyes.
"It doesn't bring the loved ones back but it was just to say Everton stand alongside Liverpool in the travesty of justice they have had.
"We can't make it better for them but it was just to show we are supportive and behind them and just to say 'well done' (for getting to the truth)."
