Defeat would have been harsh on Barca on Sunday, having been denied the lead in a highly controversial moment before half-time with replays clearly showing Messi's shot crossed the line. There is no longer any argument against goalline technology with Spanish football exposed as well behind the times in failing to award Barcelona's opener against Valencia in Sunday's clash of the top two.
Lionel Messi's shot squirmed through the gloves of Neto and over the line before the keeper scooped the ball out. The referee, who was outside the penalty area, waved play on, much to the fury of Barca's players.
The incident clearly upset Barca as Valencia went on to take the lead, Rodrigo pouncing from close range following Jose Luis Gaya's low cross before Alba's volley brought the visitors back on level
Here we bring relive five famous disallowed goals in history that should've counted after passing the line but were called off by the officials. Most of them happened before the advent of goal-line technology while Barcelona's at Valencia and the one at Real Betis last season are the only incidents after the introduction of goal-line technology.
Man United v Milan (European Cup, semi-final 1969)
Two goals down from the first leg at San Siro, United gained hope from a Bobby Charlton goal before a late goalmouth scramble resulted in Law poking the ball over the line for the " equaliser
" which would have taken the game into extra-time.
A Milan defender lying on the floor managed to hook the ball back, however, and the French referee waved play on. Replays showed the ball had crossed the line by some distance but the holders were on their way out of the competition 2-1 on aggregate.
Chesterfield v Middlesbrough (FA Cup semi-final 1997)
With Chesterfield leading 2-1 at home John Howard fired a shot against the Boro crossbar that rebounded down and in before bouncing out. The goal was not given, though television replays clearly showed the ball had crossed the line. Instead of going 3-1 up Chesterfield had to score a dramatic late equaliser
to earn a replay but they lost it 3-0.
Real Betis v Barcelona (La Liga 2016/17)
The Barcelona-based press were calling for goal-line technology on Monday morning after the side were denied a clear goal in their 1-1 draw at Real Betis, leaving them four points adrift of leaders Real Madrid. The incident came in the 75th minute of the game at Betis' Benito Villamarin stadium as Barcelona pursued an equaliser
, and Jordi Alba thought he had drawn his side level when his shot clearly crossed the line.
But defender Aissa Mandi hooked the ball out of the goalmouth before any of the match officials were in a position to unequivocally award the goal, and the controversy dominated the front pages of Monday's Spanish papers.
The full-back's 'ghost goal' was not the only mistake the officials were accused of making during the costly draw in Barcelona's pursuit of the title, as the paper also criticise Hernandez Hernandez for not awarding the visitors a penalty for a foul on Neymar.
Nigeria v Cameroon (AFCON 2OOO final)
Nigerians were in a state of shock and grief at the Super Eagles' loss in the final of African Nations Cup against Cameroon in 200 with widespread criticism of the conduct of the game's Tunisian referee Mourad Daami who disallowed Ikpeba's penalty which cannoned off the crossbar.
The Super Eagles' defeat to Cameroon could go down as one of football's
great injustices. Nigeria fought back from two goals behind to force a penalty shoot-out - only for Victor Ikpeba's fourth spot-kick to be ruled out.
Television replays showed the ball crossed the line but the miss cost Nigeria the cup as Cameroon captain Rigobert Song slotted in the winner. Adding salt to Nigeria's wounds, Cameroon got to keep the trophy after winning the cup three times, all against Nigeria.
England v Germany (2010 FIFA World Cup)
Frank Lampard’s shot that bounced a foot behind the line shone a floodlight on the illegitimacy of Fifa’s intransigence over goal-line technology. Lampard scored a valid goal in the 39th minute that would have brought England level. The shameful, avoidable error had a material impact on the outcome.
With the Three Lions 2-0 down in their last-16 clash in Bloemfontein, Matthew Upson pulled a goal back and Lampard looked to have equalised
when his long-range effort rebounded off the bar and over the line - only for referee Jorge Larrionda to disallow the strike.
England ended up losing the game by 4-1, but the controversy that ensued was instrumental in Fifa's decision to introduce goal-line technology for Brazil 2014. Germany will claim justice was done 44 years after England benefited from the doubt at Wembley. The difference is when the Soviet linesman was working the line there were no reliable aids to determine the trajectory of Geoff Hurst’s shot that cannoned down off the bar.
