An Arsenal fan suffered a suspected stab wound in a clash with Roma's notorious 'Ultra' hooligans before Wednesday night's game, which saw the Italians eventually eliminated following extra-time and penalties.

It was not the first time travelling supporters have been hurt in the city, with Manchester United supporters twice targeted over the last two seasons, and there have been calls for the showpiece match in May to be switched to another host venue.

However, asked if the location should be changed, Wenger said: "No, even if I am conscious that what happened is not acceptable.

"It has, of course, to be investigated, but I believe that is purely down to Roma's supporters.

"I have been to many Champions League finals, and it is always a much more neutral and corporate atmosphere in the final.

"You have people from all over the world who want to see the European Cup final, and I do not think that it will face the same problems."

Wenger added: "It is a big achievement for anybody [stadium] to get the Champions League final. I am not scared about the security now Roma are out for that game."

Arsenal are one of four English sides into the quarter-finals, along with holders Manchester United, last season's runners-up Chelsea and the 2005 winners Liverpool.

Wenger, though, feels Spanish giants Barcelona - who have former Gunner Thierry Henry in their team - are the team to avoid in next week's draw.

"Barcelona had the most convincing win and have scored more goals than anyone else in Europe," he said.

"They are considered by many people, understandably, to be the favourites.

"But it is a cup game. We saw that against Roma.

"We did not take advantage of the chances we created in the first leg and nearly paid for it in the second tie. You have to be efficient from now on."

Wenger declared: "No matter who we get we want to knock them out."
