The 33-year-old was named Player of the Year by both the fans and players last season.
"You're always looking and thinking 'oh right, he has come in to replace me'," he said.
"I am one of these people that thinks it is a clean slate. Last season has gone now and I've got to prove myself again.
"I'll come in, work hard from the start, give 100% and hopefully that will be enough.
"I mean, it has been a good two years. Last year was a bit up and down in terms of me going away on loan and not really knowing where I was going to end up.
"But it finished on a high and I am just delighted I managed to secure another year at QPR and in the Premier League as well."
