Leicester manager Nigel Pearson called for video technology to help prevent the sort of injustice which could have resulted in his side being knocked out of the FA Cup instead of going on to produce a thrilling stoppage-time 2-1 victory over Tottenham at White Hart Lane.
The Foxes had been trailing to a penalty from Andros Townsend but felt they should have been given a spot-kick themselves just ahead of halftime.
Spurs goalkeeper Michel Vorm -- who had earlier made two good saves -- looked to have tripped Andrej Kramaric. However, referee Robert Madley instead showed the Foxes' record 9 million-pound signing a yellow card for diving rather than a red to the Dutchman and signalling a penalty.
The visitors, though, were eventually rewarded for their continued industry with seven minutes left when Leonardo Ulloa swept the ball into the bottom corner.
There was then late drama in stoppage time when Vorm allowed a scuffed shot from Jeff Schlupp to squirm over the line.
Pearson was pleased his side got their rewards, but also felt the match could have hinged on such a key decision.
"I am big believer in the need to introduce more technology to aid the officials," said the Leicester manager. "There is no point ranting and raving about it. I can say it was unfortunate today, however these things can cost people their jobs.
"If it was a Premier League game which we lose because of a decision like that, maybe I would be talking a bit differently.
"The media have monitors to see the incidents, and I think in the Premier League there should be no issue in having another official who has the capability to see replays -- once the referee has blown the whistle, it would not take too long to refer it.
"For the supporters as well, it would clarify situations in the game and there would not be ill feeling in the ground. I don't see why we don't look to utilise it more."
Pearson had made several changes to his starting XI and felt the team deserved credit for their efforts, which came on the back of struggles for consistency in the Premier League.
"It was a really good win for us, because we need to find a way to win more games," he said. "I know they made a lot of changes, but hopefully this will be a positive influence for the rest of the season."
Pearson insisted there should be no issue over the selection of utility man Schlupp, who was ruled out of travelling to the African Nations Cup with Ghana because of a knee injury picked up on New Year's Day at Liverpool.
"We operated well within our rights. The regulations are there to protect players, clubs and national sides," he said. "We have been totally transparent about the situation throughout.
"He did not take part in their training camp and on medical grounds was advised not to fly. That is our own medical team and an independent medical assessment which the Ghana federation had done and they came to exactly the same conclusion.
"I know it has got legs because he has scored the winner today, there will probably be more about it, but I am not concerned by any negativity.
"I am delighted he is with us and has shown what a talent he is."
