Arsene Wenger has reiterated his hopes for video technology to be introduced to football, after a controversial Easter programme.
Referees were under the spotlight last week after debatable decisions in games involving Manchester United and QPR, as well as Chelsea's game with Wigan.
On Wednesday, Manchester United were again involved in controversy as they were denied a penalty for a handball that was clearly shown on television replays.
The Arsenal manager believes the sport's governing body needs to act as soon as possible to 'help' the match officials.
He said: "Last weekend was a very, very bad weekend. The football authorities on a global scale have to sit together and see how we can improve.
"There are some immediate decisions to make but as well it is time for us to help the referees. To all be united and have a less conservative approach and finally opt for video.
"Video will help the referees, not question their authority. It will give them more credit, more authority and less mistakes. (We need) instant video replays on the demand of the referee."
Critics claim that video technology would slow down the game, while others suggest it could affect the divide between the professional and amateur game.
But Wenger disputes the criticism and believes it could actually speed up general play.
He added: "It would not stop the game. It would sometimes give a bigger flow to the game. Why? Because if I am a linesman and an offside decision is a 50-50 I'm tempted to stop the game.
"If I know I have a video behind me I am tempted to let it go if I'm convinced it is a real 50-50 and you could improve the flow of the game and check after.
"Football is the first sport in the world today but we have to accept we have the most conservative approach to the game than any other sport. It can be a strength but on the refereeing side I think it is a weakness.
"I don't think referees are bad. I just think the game is so quick. It is impossible for a human being to see everything no matter how good you are.
"Out of 100 situations (with instant videos) you would be less wrong than you would be today because you would have help."
