Arsene Wenger believes UEFA need to look at the way they choose referees after accusing Sweden's Martin Hansson of being "incompetent". The Arsenal manager Wenger slammed Europe's referees after reiterating his view that Hansson was wrong to allow Porto's second goal on Wednesday after giving an indirect free-kick in the box following a back pass by Sol Campbell which goalkeeper Fabianski picked up.
Wenger said: "It has to be clarified first of all how they nominate referees for games. They (UEFA) have to be much more open on how they rate their referees.
"Where is the ranking of the referees? I believe too much has gone on in the last 30 years. What has happened is not good for football."
When asked if Hansson, who missed Thierry Henry's notorious hand ball in France's World Cup qualifier against the Republic of Ireland, should be refereeing at Champions League level Wenger said: "I trust the referees to do their job and to do it well. I never ask who the referee is before a game but in this case I cannot say that he made everything right because he was wrong.
"It's not my job to judge is he good enough or not, I just feel in that game he has shown he is not competent.
"He made at least five technical mistakes for a referee. He made a massive mistake. You cannot give a quick free-kick once the referee is in the middle of the action.
"Once he is there in the middle, where the free-kick is, he cannot anymore give a free-kick, he has to make sure the opponent is at nine metres distance.
"I believe he is incompetent or dishonest, so I prefer to believe he is not competent."
