Rodri claimed Manchester is “becoming more blue” as he was officially unveiled as Manchester City’s record signing on Thursday.
The Premier League champions paid a £62.8million release clause to buy the Spain international from Atletico Madrid.
In previous years, Manchester United were the area’s biggest attraction for top players, but Rodri feels that is changing with City now a powerful force.
The 23-year-old said: “I think City, this last five or six years, have changed the story of football here, not only in Manchester but the whole of England.
“I don’t look for the team, for the club, I look for the challenge on the sporting front and that is why I moved here.
“I love the city, I love Manchester. I talked with some guys and I think it is becoming more blue.
“I chose City because of the football challenge and the way these last two years they have won lots of things. That says this team is growing every year.”
Under the guidance of Pep Guardiola, City have won back-to-back Premier League titles, with last season’s success coming as part of a domestic treble.
Rodri is relishing the chance to work under the inspirational former Barcelona and Bayern Munich boss.
He said: “I think he is the greatest coach in the world and that is what made me come here.
“I want to learn and grow as a football player. I am very young, I have lots of things to do, to grow, to learn and I think with this coach, Pep, I am going to grow here.”
