Langfield is in his ninth season at Aberdeen and he has held off the challenge of Nicky Weaver to remain No.1 keeper at Pittodrie.
The 33-year-old concedes he may not be everyone's favourite at Aberdeen, but that his commitment to the club cannot be questioned.
"I have not given it any thought. I am just focusing on now and enjoying my football," Langfield told the Daily Record.
"People can talk negatively about me but one thing I guarantee is every time I put on an Aberdeen shirt I will give 100 per cent.
"I may not be everyone's favourite but no one can doubt my commitment to the club.
"I am close to playing 300 games for Aberdeen. If I do reach that it would be a great achievement for me. It's always a challenge whenever a new keeper and manager come in to a club.
"Hopefully the gaffer can see by my performances how much I want to play for him."
