Tottenham Hotspur manager Harry Redknapp believes referee Martin Atkinson guessed whether Juan Mata's shot crossed the line in the FA Cup semi-final.
The Chelsea midfielder's goal-bound effort sparked a melee in the six-yard area, with Atkinson awarding the goal despite the lack of conclusive evidence.
Having spoken to the official after the game, which saw the Blues thrash Spurs 5-1, Redknapp revealed Atkinson was inconsolable following the error.
“I spoke to him [Atkinson] – he says he feels worse than I do,” Redknapp said.
“I said, ’I don’t think so’, but he says he feels bad. He knows he’s made a mistake and he says he’ll have a bad week as well. He can’t have been sure. He’s just made a mistake, unfortunately. It was nowhere near a goal. It was an honest mistake but nowhere near over the line.
“He’s not done it on purpose. I don’t see how he can give the goal. It’s not as if it’s gone in and someone’s kicked it away, it’s so quick. There were bodies on the line and the ball couldn’t possibly get over.”
The incident has sparked further debate over the introduction of goal-line technology, with the International Football Association Board set to decide on July 2 whether a system can be introduced.
Tests of two chosen systems will continue until the July summit, with calls for the introduction of the technology continuing to swell. Redknapp says high-profile incidents such as these can't continue to occur.
“Goal-line technology has to come into the game,” Redknapp said.
“You can’t keep having situations like that. It was key. It’s got to come in. You can’t carry on like this, with important decisions not being correct. Referees don’t make mistakes purposefully.”
