Johnson logged an incredible eight miles in his last game against Manchester United and his legwork saw him named in England's provisional squad for the match against Montenegro eight days ago.
Johnson, 24, said "That's my game - working hard. I'm a box-to-box player and I never stop running.
"I grew up watching people like Frank Lampard play and now I am on the same pitch as them.
"But so far I think I've done pretty well and I'm holding my own.
"It's a massive boost just to know that I am being considered for England, but I'm not going to get carried away.
"Hopefully Fabio Capello will watch me again, but I will just carry on doing what I have been doing and let everything else take care of itself."
