The centre-back, 30, has featured sporadically over the past two seasons.
But he is confident this is not the twilight of his career.
"I'm patient. I'm working behind closed doors a lot and sometimes it is frustrating when you don't play," he told Sky Sports.
"You are fighting with yourself in your mind, asking 'Why not?'. But you are accepting it, you are moving on and from my personal point of view I want to be better every day in the training sessions.
"The day will come when I will get again the chance so I am happy that I am not injured - which is the most important thing - and I'm also happy that we are all together and we have a full squad at the moment.
"Of course I want to be in the team that wins many trophies. I think, and I feel, that I have quite a lot of years to give especially in professional football. I'm 30, so another good five years.
"I don't think I'm just a throwaway. If the club needs me I am here, I am happy. But you never know what can happen in the summer. At the moment I am just focused on the point where I can say I made it [as part of a great team]."
