Macario, who has featured twice for Chelsea since her return from injury, will hope to play some part when Emma Hayes' side take on the Gunners at Molineux in the Conti Cup final this afternoon.
She added: "It is a big derby, I guess it would be even more special if we were able to win it against Arsenal, but no matter who it's against, no matter what game, we want to win. I don't think my teammates need to really tell me how much it means, we're all competitors and what we want to do every single day is win, compete, dominate and set the Chelsea standard."
