Redknapp has signed a 2½-year contract at Loftus Road.
Asked if he will remain with the club if they get relegated, he said: “I don’t even want to think about that.
“I have not come here for just a short-term fix. I want to build a team and stay for a few years. Keep them up this year and go from there.
“You look at the clubs who are doing OK — take West Brom. They have had three or four years of building. They are not just throwing a group of players together. They are building a team.”
