Robinho insists he can be declared the world's best player by playing in a Manchester City shirt.
He told The Sun: "Yes, it can be done, and it will be done. You can be sure. I want to be the world's No 1.
"Many people think it has become difficult because of the team but I think it's even easier because at Manchester City I will always start.
"At Madrid I was only used for the important matches.
"In terms of marketing, it may be the best. However, for me, the best team is the one where you get to play. It's no good if you are at a so-called great team but spend your time sitting on a bench."
Robinho 24, and just 5ft 7in, insists he is loving life in Manchester and revealed how he should be fluent in English by the end of the season.
But he has warned City he only plans to stay for another five years at the most.
He added: "We players can never stop dreaming. I want to win the World Cup. When I'm 29 or 30 I want to go back to Santos and win them the Libertadores. My English is still weak, but I intend to be fluent in six months.
"You'll see. I think speaking English is beautiful. I am studying the language with my wife."
