The Rs have been busy in the transfer market thus far, signing Park Ji-Sung from Manchester United and wrapping up a permanent deal for Samba Diakite, who was on loan at the club last season from Nancy.
But the 34-year-old is confident he can still be a key player for Hughes, and is hopeful of securing a regular spot in the side.
"There are players that can cover all positions and to get players from the likes of Manchester United coming here, it's great for the club," he told Sky Sports.
"Competition is going to be unbelievable. Last year was fantastic to play in. I'm hopeful that I can stick around and prove a point next season.
"I'm hopeful that's going to be the case and until I'm told otherwise, I'll carry on doing what I'm doing. I've got confidence in my own ability, but it's up to what the manager sees.
"Until I'm told otherwise, I'll just crack on, like I have done throughout my career."
