Arsène Wenger says beating Manchester United at Old Trafford provides the benchmark for a successful season.
The Gunners visit the home of the champions on Sunday and have not won there since September 2006.
But the Frenchman believes his team will gain "confidence and credit" if they take three points off David Moyes' side.
"It is still one of the benchmarks of the season where you judge how strong you are," said Wenger. "People analyse everything, your behaviour and draw conclusions after the game. It is of course still one of the big games.
"You can gain confidence and credit for your behaviour.
"We had periods where we did very well at Old Trafford and recently, yes, we have not done so well," Wenger added. "It is a good opportunity to show that we have improved and that we can win there.
"That is our target, to go there and win the game."
