Rodwell, who joined City in a big money move from Everton during the summer transfer window, has spoken out to play down Johnson's suggestions that home-grown players are continually overlooked for expensive foreign signings at the Etihad Stadium.
England international winger Johnson made the claim following his August switch to hometown club Sunderland, while 21-year-old midfielder Rodwell is adamant that a move to the Premier League champions will benefit his career on both the domestic and international front.
Rodwell, who is set to line up for England's Under-21 side against Serbia in a Euro 2013 qualification play-off at Norwich City's Carrow Road on Friday, said: "I'm young and English. I've not got a bad word to say about City. If they want you and sign you, then they have got intent for you.
"I was not guaranteed a starting place at Everton. I had a lot of injuries, Darron Gibson and Marouane Fellaini were in form, so it was a push for me to get in that side. But when the champions come knocking, it's hard to refuse."
Rodwell did admit finding it 'hard to adjust' to life at City, having spent his playing career at Goodison Park since the age of seven.
He added: "Being there 14 years meant any move was going to be big. The methods and styles are very different. The respective managers are very different. The standard of training is amazing."
