• Arsenal manager says referees need help to make decisions • 'Video will help the referees, not question their authority'

Arsène Wenger wants referees to be allowed to stop the game and consult video technology to make instant decisions in the Premier League.

The Arsenal manager's call comes after a week of high-profile mistakes by match officials which saw two offside goals awarded to Chelsea against Wigan last Saturday and Manchester United deprived of a clear hand-ball penalty against Wigan on Wednesday.

Wenger believes it is time football's administrators fast-tracked video assistance for beleaguered referees.

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."

Wenger denies it would slow down the game, which has been a main concern of the Fifa president, Sepp Blatter.

Wenger said: "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."

Wenger also believes there should be a much larger pool of referees available for Premier League duty.

He added: "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."

Arsenal play Wigan on Monday and the full-back Kieran Gibbs and the forward Gervinho could be available after recovering from groin and ankle injuries respectively. Laurent Koscielny is suspended.

Wenger was guarded on whether Jack Wilshere, who is recovering from a serious ankle injury, would play any part in the rest of the season.

"He is making slow progress," Wenger said. "We will have to monitor the situation. The next three weeks would be decisive. I will not take any risk with him."

Meanwhile, Wenger has challenged the former Arsenal defender Sol Campbell to put his money where his mouth is.

Campbell has queried Arsenal's ambition and urged them to sign proven quality if they are to challenge for trophies next season.

Wenger said: "Sol Campbell has a lot of money. His gifts are welcome. If he gives us money I will spend it. The best way to give advice is to show example."
