The Gunners slumped to a second successive season without silverware, finishing fourth in the Premiership and a demoralising 21 points behind champions Manchester United.

Boss Arsene Wenger recently branded the campaign a failure and Henry agrees, adding Arsenal have endured disappointment for the last two years.

But while the French striker is hurt by the gulf that has opened up between his side and title rivals United and Chelsea, past experience has taught him fortunes can quickly change.

"Arsenal have not had a successful season and last season was the same. For me a successful season is bringing home silverware," he told Arsenal TV.

"I'm not going to hide behind some of the reasons for that, although I agree with what people are saying.

"I agree that when you move to a new stadium you need to adapt to it and I agree that we are a young squad.

"But I'd be lying if I said we have been successful - we haven't been successful for two years.

"My first season at Arsenal was not a successful one and the second one was the same. Then we went on to win the double in 2002 so you never know what can happen.

"If everybody is fit and fresh I don't even think about not winning the title. I think we're as good as Chelsea, Manchester United and Liverpool.

"I can understand losing the title race by a single goal but to be so far behind is hard to take.

"But we've been here before and we've come out on top before. What comes around goes around.

"Manchester United have won the Premiership this year but who would have said that they wouldn't win it for three years in a row?

"Next season is a new season and it's up to us to make it happen."

Arsenal have struggled to settle at the Emirates Stadium after leaving Highbury last summer, winning three fewer home games than United.

Henry admits the move has proved more problematic than he expected with the Gunners' lack of history at their new ground robbing the club of some of its fear factor.

"I thought going to a bigger stadium would be easier than playing at Highbury but we've realised that's not the case - it's more difficult," he said.

"I spoke to the boss about it and he raised a great point by saying that when teams come to the Emirates they have no history of getting hammered.

"They come fresh and have no history of losing a game. The move hasn't been as easy as everyone thought it would be."

Henry believes Arsenal have been architects of their own downfall this season with a lack of width and poor starts to matches hampering their progress.

"It's a paradox. The Highbury pitch was smaller but we were finding more space," he said.

"Now nobody wants to stay on the wing to stretch a team and that makes a great difference.

"If you're a full-back and your winger has already gone inside then it makes it easy for defenders.

"But if your winger is always on the line and ready to make runs behind you then defenders get scared.

"There was just one game this season when we went back to the dressing room 2-0 up at half-time - against Watford.

"No disrespect to Watford but they're a team that was relegated a few weeks before the end of the season. We've never approached a game well at home."
