The Gunners had won their previous seven league games in a row before losing to Mark Hughes' men but the Frenchman believes his team have the experience to bounce back on Sunday.
"It's a good opportunity to put things right again, of course," he told reporters.
"I believe that we will see a different Arsenal on Sunday but I can tell you as well that it will be needed.
"We have played well against the top teams and that is our target again. We know how to respond, as we have been exposed to this situation before this season."

The 62-year old admitted his team were below par at Loftus Road but praised the hosts' potency in front of goal.
"I've said many times we have to stay humble and focused and I feel that the focus was missing a little bit," he continued.
"You cannot lose the game in the way we did. They take the ball, they put it in the top corner, you accept it.
"But the way we gave the ball away, I felt we lacked something and we cannot deny that."
