Need a category that shows most viewed posts

Hi!
I need to create a category-page that shows most viewed posts. I’ve searched around a bit, and can only find how to get most viewed posts from a specific category, or create a page that shows most viewed posts, and that’s not what I want. I need to create a category-looking page, because on my theme, the category-page is totally different shown than a normal page.
Thank you for any help.
