The Danish forward signed a three-year contract with the Midlands club earlier this week.
The 22-year-old told Danish newspaper Bold: "They see me playing different positions rather than just as a striker as the experts say.
"They think I'm fast enough to play on the wing and I agree. I'm also able to play in the hole behind the striker.
"Personally I've always seen myself as a player in the hole behind the striker because of my finishing ability outside the area and Villa sees me the same way, as a flexible striker. But my main aim is first team football and I enjoy playing any position."
Helenius scored 40 goals in 102 appearances for his previous club, Aalborg.
