Playing a bit part role in Manchester City's title-winning campaign last season, Johnson failed to make Roy Hodgson's England squad for Euro 2012.
His future at the Etihad Stadium was heavily speculated prior to his move to Sunderland this summer, and the winger told the Daily Express that his desire to play for the Three Lions factored into his decision to leave the Premier League champions.
"If you're on the bench and not even playing, then I think it's only right that the other person plays, isn't it? It plays a little bit on your mind," Johnson revealed.
"The England manager has come out and said he wants his players to be playing regularly, that you can't sit on the bench forever, so that's another reason for me to come to Sunderland and hopefully get more games and keep carrying on playing for England. Hopefully I'll be going to the World Cup in Brazil."
Despite his City career ending on a disappointing note, Johnson insisted he had no hard feelings toward Mancini.
"City are always buying whoever and spending whatever, so there's always going to be someone coming in to take your place, so I owed it myself to move on and get games and try and show everyone what I can do again," he stated.
The former Middlesbrough player also expressed his excitement at the opportunity to start afresh at Sunderland.
"You want to win trophies and medals as a player, but sometimes you've got to be playing and enjoy playing football. Coming to Sunderland means I can enjoy it again," Johnson said.
"When you're getting dropped and things, all the disappointments, not knowing if you're going to play or be sat in the stands, that was a major factor in coming here. Playing football and getting back to enjoying it. I want the confidence put back into my game so I can express myself fully."
