The Brazilian left-back is currently plying his trade in Italy with Juventus and has impressed for the Old Lady this season.
The Sun have recently claimed that City are set to bid £50million for attacking full-back. With City struggling defensively this season, signing a left-back will surely be a position that will be looked at by Guardiola.
His attacking prowess and his defensive ability would make him a good replacement for out of contract Gael Clichy, who looks likely to leave the Etihad at the end of the season.
Alternative signing: Sead Kolasinac (Schalke) – The left-back is coming to the end of his contract at Schalke and he would certainly be a cheaper option than Sandro.
