Manchester City are allegedly interested in signing Benfica defender Alex Grimaldo during the summer transfer season.
Despite winning the Premier League title last season, Pep Guardiola rotated his left-backs.
While Man City have plenty of options on that side of the game, Benjamin Mendy has been linked with a move away from the Etihad Stadium in the coming weeks.
According to Portuguese journalist Pedro Almeira, City has initiated talks over Grimaldo's availability.
Since joining Benfica in 2016, the 25-year-old, who came via the Barcelona academy system, has made 169 appearances in all competitions.
The Portuguese giants are reportedly wanting around €30 million (£25.6 million) for a player with two years left on his contract.
