City spent big on the Brazilian midfielder last summer after fending off interest from rival clubs in England to put a deal in place with Shakhtar Donetsk.
Fernandinho has settled quickly in new surroundings, becoming a key figure in Manuel Pellegrini's plans.
A Premier League platform has also allowed the 28-year-old to play his way back into the Brazil squad in time for a home World Cup.
He could not be happier with how things have gone and is convinced that he made the right choice in joining City at this stage of his career.
Fernandinho told Globo Esporte: "I have always been focused, regardless of where I am, and that's very important for a player that likes to win games and titles.
"Manchester is a very calm city, it allows you to focus on your work.
"My main goal was to return to the national team. I knew that if I shone in a strong league, I could be called up.
"Time was short and the World Cup is just around the corner, but I managed to become a starter, establish myself and gain the affection and respect of fans in an important football country like England.
"Now I want to play the World Cup, play the full five years of my contract in Manchester, a city and club that has received me very well and has allowed me to grow and fight for important titles."
