Man Utd's Van Persie visits home Arsenal dressing room after draw
Van Persie refused to celebrate converting his spot kick.
Wenger revealed his former striker spent some time in the Arsenal dressing room after the match, joking: "Our food is better in our dressing room than their dressing room".
Wenger said: "That equaliser played a big part in the game. It put us in a difficult position but overall I can only praise the players for the effort and dynamic and desire we put in. Let's keep it going like that and we'll have a chance to be where we want to be."
