The England under-21 international has been linked with a £2.4m move to QPR after earning rave reviews since joining the club on loan last month.
But he told the Portsmouth News: "I think QPR will spend big in January. They've got the money to do it now and they're an ambitious club. I don't know anything about me joining permanently though. I wouldn't be interested anyway. I definitely see my future at Portsmouth, this is just an experience for me. I just want to go out and get games and show everyone what I can do."
