Toure said: "Manchester City are always a club that wants important players like Bony and Aguero, they always want to progress and be at the top of the Premier League.
"If you want to be at the top of the Premier League you need to sign the top players and Bony is one of them at the moment.
"t will be tough to win the title again as Chelsea are in a good moment.
"It is not finished and we need to compete well and do the business and again."
