Arsène Wenger believes that technology could provide a better solution to the refereeing mistakes that can blight football.

Arsenal were on the receiving end of a poor call on Tuesday night when Carlos Vela’s penalty appeal was turned down at Braga. The Portuguese champions went on to win 2-0, a result that leaves Arsenal’s European hopes dependent on their last group stage fixture.

UEFA have introduced extra officials behind the goal line for Champions League games this season but the foul on Vela was still missed. Wenger can certainly see the flaws in the new system.

"It's only my opinion on this game [in Braga] but on the night you had some surprising decisions,” said the manager.

"It's not an absolutely rational argument that [extra officials] can cut the mistakes because they can make errors as well and you can add errors to errors that exist already.

"They are human beings who make mistakes as well. We have seen as well in some games that they made a wrong decision when the referee made it right at the start.

"At the moment, everybody would accept who watches the game that it's worth attempting but it's not conclusive in a positive way at the moment. We have to wait a little bit more."

Wenger has advocated the use of video replays to assist officials for many years now. He has seen nothing to alter his view.

"I've always been for it [the use of technology] and you will not be surprised if I do not change my mind,” he said.

"But I'm ready to accept everything that makes the decision better and that gives help to the referee.

"If the fifth official is the answer to it, I'm happy. But to me, watching all the games I've seen, it does not look at the moment a conclusive answer."
