It's been suggested United could snap up Filling and loan him to sister club Lausanne for two years until he can move to England as an 18 year-old.
Asked about the rumours, Filling told Expressen: "Yes (I know about the rumours), but it's nothing special.
"I don't know much about it. I'm focused on AIK. That's all my focus. I don't know anything. So I don't think about it that much.
"I want to do as well as I can in every match. Every chance I get. Continue to deliver more points. That's it."
