The England number one has received some negative responses for his performances this season but he feels that is part and parcel of constantly being in the limelight.
"If you weren't doing well, and winning things, then people wouldn't be interested in what you're doing," he said.
"People are paid to make comments and do punditry but you've got to be strong and confident that you can turn up week in, week out and give the best you've got.
"Of course (I feel I'm playing well). I work hard, but sometimes I don't save it, it's as simple as that, it's not through lack of effort or concentration.
"You'd like to be perfect and make every save but, as much as we try to be, it's not going to happen."
