Dani Alves is the shock name on Pep Guardiola's radar if Manchester City sell Danilo this summer.
Alves, a free agent after leaving Paris Saint-Germain, was set to sign for City two years ago before performing a late U-turn and moving to the French capital instead.
That has not deterred Guardiola, however, as the Premier League champions keep their eye on potential right backs this month.
A move for Alves is considered unlikely at this stage - not least because Danilo has not secured a switch away from the Etihad Stadium.
Inter Milan and Juventus have both been interested in Danilo, who joined City for £26million after Alves rejected a move in 2017.
Alves, 36, played under Guardiola at Barcelona and was Brazil captain as they lifted the Copa America.
