The 24-year-old winger struggled to cement his place in City's team last season, and has been linked with moves away from the Etihad, but insists he is committed to the club.
The talented winger has spoken of his determination to prove his worth and will look to put a disappointing campaign behind him and impress in 2012-13.
Johnson told the club's official website: “It was pretty hard watching from the side-lines because obviously you want to be out there, helping the lads.
“It’s tough, but you have to keep plugging away and just give your all. We won the title which was the main thing, but obviously you want to feel you’ve played your part, too.
“Things can change pretty quickly in football and this is a new season and we all start with a clean slate once again. What I need to do is respond, try even harder and react positively.
“On a personal level, it was a disappointing end to the season for me because I wasn’t playing for City and then I missed out on Euro 2012 which hurt me a lot, but the key is to bounce back and not dwell on things.
“I love everything about this club – the lads, the people around it and the supporters have always been brilliant towards me. I’m settled where I live so I just need to get out there and play – as a footballer, that’s all I want to do.”
The wide man also commented on his omission from Roy Hodgson's Euro 2012 squad, and believes he had done enough last season to earn his spot for the tournament.
Johnson said: “I’ll be quite honest and say I really think I should have been selected because I played five times in the qualifiers and scored two goals so I thought I’d proved my worth.

“When I played for City last season I scored a few goals and made a few as well so it took me a while to accept not being able to represent my county at a major championship because the same thing happened at the World Cup two years ago.
“To be fair, Roy Hodgson has been brilliant with me and phoned me to say that he still wanted me to come to Norway and train before the Euros began. As far as I’m concerned, I start my bid for the 2014 World Cup from now.”
