Manchester City are said to be "very interested" in Boca Juniors duo Valentin Barco and Exequiel Zeballos.
The Blues are no strangers to the South American market and recently secured the signing of River Plate star Julian Alvarez.
He'll join fellow South American export Kayky at the Etihad Stadium. The 18-year-old is beginning to make waves in the City first-team set-up and was included in the squad that travelled to Sporting Lisbon for their Champions League tie on Tuesday.
