Shaun Derry has signed a one-year contract extension at QPR.The midfielder’s new deal, which expires in 2013, is his reward for an impressive start to the season as well as his role in helping Rangers win promotion last term.Derry, 33, was initially signed in 2010 by boss Neil Warnock – who also managed him at Crystal Palace– as a squad player but turned out to be a pivotal first-team regular.AdChoices广告And this season he is desperate to go one better and prove his doubters wrong by performing in the Premier League. “I always like proving people wrong and I take encouragement from the manager’s words,” Derry said last month.“When he said I was going to be a squad player, I wanted to prove him wrong and this year I don’t want to be a squad player in the Premier League – I want one of those starting places and I want to keep it.“I’m hoping the midfield role I play in will be even more relevant this season. Last season it enabled the more attacking and creative players to shine, and I’m hoping to do a similar job this year.“Time will tell. Obviously the class of opposition is going to be better, but we’ve all got something to prove and I certainly feel like I have. I want to prove people wrong again and show that I can play at that level.”Derry’s new contract is with a view to him taking a coaching role at Loftus Road in the future.
