He added: "Everyone here wants to get promoted and it's a lot like the pressure of trying to break into the top four of the Premier League at Newcastle.
"It's almost an impossible task to do that given the strength of the top four but they live in hope they can do it and we are living in hope we can join the teams in the Premier League.
"Kevin Keegan offered me another year at Newcastle and very kindly kept that offer open while I talked to other clubs.
"QPR had the ambition and the infrastructure, plus they were offering me first team football so, in the end, it was the right decision to move.
"But just as at Newcastle, we are trying to get into the unknown. I know QPR were in the Premier League a while ago but it's a whole different ball game now.
"We have got to try and match the board's ambition. We've done that so far and, hopefully, we can carry it on."
