Fulham were the latest side to take what could prove to be crucial points off misfiring Arsenal, who failed to find the net for the fourth successive Barclays Premier League game.

It is a run - the worst in more than 15 seasons - which has dealt a near fatal blow to their aspirations of regaining a place in the top four, and also allowed Everton to close in on fifth place.

Robin van Persie was twice denied by Fulham keeper Mark Schwarzer, who also produced a brilliant goalline clearance to block Abou Diaby's second-half header as the Gunners fans - who have now not seen a league goal at home since January 10 - were left frustrated once again.

Following the final whistle, before which many had already headed for the exit, the supporters vented their disappointment towards the team - and there were even a few isolated calls for Wenger to go.

However, the Gunners boss - who has transformed the club over the last decade - insisted he must focus only on guiding his men through what is proving to be a testing period.

"I don't know [whether the fans are losing faith]. That is not my worry," said Wenger.

"What is important is that I do what I believe is right and we keep going, that we show great attitude and do our job as well as we can, then let everybody judge and have an opinion.

"I believe it's not the biggest problem, not the biggest worry. The biggest worry is that we don't win games that we should win.

"We have been through difficult times, but it's an opportunity to show that you are strong enough to come through it."

Wenger is determined not to make a big issue of his team's goal drought, and believes the character of his squad is strong.

"I feel the players are showing enough desire, but when you don't get the results the first thing people always doubt is the desire," he said.

"I want to win the games and when we don't win the games, it's disappointing.

"Every defeat or every time we don't have a victory is tough.

"At the moment it's not satisfying, but we will see how strong we are until the end of the season."

Of course, just where Arsenal will finish come May remains to be seen, but it now seems an uphill battle for the Gunners to force themselves back into the shake-up for Champions League qualification.

Wenger, though, remains focused on that very goal.

He said: "You know how much I want to get into the Champions League. For me, it is not important - it is vital. But you can only play your games and try to win them.

"I want to be in the Champions League because it's the best I can be. If I'm not, then I'm not happy. It's as simple as that.

"You don't play football to be average. I don't manage in the game to be average, and the players want to play at the top."

Arsenal head to bottom club West Brom on Tuesday night, but Wenger accepts given their injury situation, he has few options available.

"We don't have many opportunities to change things round at the moment," he said. "So we will keep the positives from what we do well and go into the next game to win it.

"What is good in football is that in three days the story can be completely different."

Full-back Gael Clichy insisted the team are up for the battle.

"We have to keep fighting," he said. "We know that other teams will drops points as well, this season is a bizarre season and we have to keep trying.

"It is just a case of this first goal. If we can score a goal in the first 20 minutes it's a different game and maybe we would finish with two or three."
