Former Arsenal captain Robin van Persie can expect a hot reception in north London, where passions still run high among some supporters over the manner in which the Holland forward left last summer in a £24million move.
"When you work somewhere abroad, you have to respect the culture of the country. That is part of the tradition of English football and I want that to be respected," said Wenger.
The Frenchman hopes Van Persie's return will not overshadow the importance of his side producing the required result as they look to close in on a top-four Barclays Premier League finish which would secure Champions League qualification.
"I am looking forward to our performance on Sunday more than anything else. You focus on your own team and it's an interesting opportunity for us to achieve something special on Sunday. We want to take this opportunity," he said.
"We respect Robin van Persie like every other player who has left us and came back to the Emirates.
"I want the player to be respected like everybody else. I always said that for every single player who left, even some of them in much more controversy than Robin van Persie."
