The 24-year old winger was used mainly as a substitute by Roberto Mancini last season and has completely fallen out of favour with the Three Lions but wants to change that next season by becoming a more consistent player.
"It was pretty hard watching from the sidelines because obviously you want to be out there, helping the lads," he told City's official website.
"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.
"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.
"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."
