He said: "I have been lucky, I have stayed away from injuries. I've got an aim to keep getting better and better as a player and keep my levels as high as I want them to be.
"I think I've just had my best ever season but I don't know when the peak will be. I hope it is still to come. I hope the peak will be over the following years.
"I see good professionals like Gianfranco Zola have fantastic seasons aged 36-37. That is where I want to be.
"I want to carry on as long as he did. No one can guess the future too much and we are always liable to form and injuries and your legs packing up when you don't expect them to go.
"But the way I feel now, the way I want to lead my life and train and play, I see myself playing for quite a long time, to the stage Gianfranco did.
"And, when I get to that stage, I want to be involved in helping younger players in the team and be a big part of the future."
