The winger points out that his return of four goals and 11 assists is sometimes overlooked.
Johnson told The Journal: "I know fans are not happy but I have scored four goals this season. I have put in more crosses than anyone else and I have had assists for 11 goals too.
"Those are the stats I prefer to concentrate on because they help give you confidence. The people who are ahead of me on the assists list are mainly at the top-five clubs.
"They are the likes of Juan Mata, Lukas Podolski, Theo Walcott, Wayne Rooney and Robin van Persie - so that is not bad company to be in - and I am the only player in that group who is in the bottom half of the table.
"People do not really see that or look at those sort of things."
