Minutes later word had spread to those watching in Stamford Bridge by radio and Twitter. Technology had ruled - and an audience of millions became aware of the latest goal-line injustice that could end up gifting Chelsea the Premier League title - all apart from referee Andre Marriner!
Sepp Blatter and Michel Platini's strong opposition to the introduction of technology will be tested again now. They want the game played by humans to be refereed by humans, but as more errors are highlighted they appear isolated in their stubborn refusal to advance the game.
Injustice: Heurelho Gomes stops the ball from crossing the line
Liverpool boss Kenny Dalglish asked yesterday just how long can the march of technology be resisted? He said: 'If the competitions are that important, then you deserve the best you can get. I don't see any reason why goal - line technology can't be there.'
The suggestion that we use the cameras already in situ - which showed without any doubt that Gomes had stopped the ball before it had crossed the goal-line - is dismissed as heresy. Such a move, even if interim would not be considered by FIFA because they see it as opening Pandora's Box, with slow-motion replays interrupting the flow of the game. But with more camera angles being available, these incidents are occurring with greater regularity.
Of course it is the IFAB (International Football Association Board) who decide on any changes to the laws of the game. FIFA have four votes - enough to veto any proposal - but they are resistant. In 2007, the Premier League tested principally Hawk-Eye, at Reading FC. Rumour had it that the experiments were proving successful when FIFA stopped it all.
Travesty: Frank Lampard's effort clearly crosses the line during the World Cup
After Frank Lampard 'scored' against Germany, FIFA announced a U-turn and manufacturers of goalline systems were invited to demonstrate their wares.
But FIFA reiterated until a 100 per cent accurate system could be found they will continue to deny what is common sense. They're out of excuses now. The technology is there and must be used for the good of the modern game.
POLL ON: THE INCIDENT
Seeing something that has not happened is just not acceptable and Mike Cairns, the assistant, will rightly be suspended.
Cairns was in the right position for an assistant; in line with the second rearmost defender to judge any potential offside. The tame shot from Frank Lampard looked to be a routine save for Heurelho Gomes but Cairns should have followed the ball down to the goal-line.
When Gomes fumbled and the ball rolled on to the goal-line Cairns was in no position to make a solid judgment and guessed.
Brave call: Mike Cairns was 35 yards away from the incident
The whole ball must be over the line, either in the air or on the ground. If assistants miss something that happens due to a poor viewing angle that is understandable. But as neither can cover the goal-line when required, surely they should be helped by technology.
How much longer can we have the ludicrous situation whereby everyone in the stadium knows if a goal has been scored EXCEPT the referee?
POLL ON: THE LAW
The law in question couldn't be simpler, but it does confuse people. The whole of the ball must have crossed the line.
LAW 10 - THE METHOD OF SCORING - A goal is scored when the whole of the ball passes over the goal-line, between the goalposts and under the crossbar, provided that no infringement of the laws of the game has been committed previously by the team scoring the goal.
POLL ON: THE ASSISTANT REF
Mike Cairns is one of the longest serving and most experienced assistants on the select group list. He is also one of the most confident, many would say arrogant.

The fact he was so adamant that he was correct to indicate the ball had crossed the goal-line, clearly telling Andre Marriner, 'Yes, yes, yes' when questioned by the referee, is no surprise.
I am not a fan of suspending or dropping officials for human errors but when one makes such a poor call there has to be consequences.
Cairns will be lucky if he gets another Premier League appointment this season and must hope Manchester United play well enough to secure the title that his error helped Chelsea to contest.
