British media reports claimed the Brazilian joined City for a fee of around 26 million pounds ($33.78 million), making him manager Guardiola's second major defensive signing in the current window following Kyle Walker's arrival earlier this month.
Danilo, who previously won two league titles in four years at Portuguese club FC Porto, will join his new team mates in their pre-season U.S. tour and could face his former club when City play Madrid on Wednesday.
