Manchester City have reportedly ramped up their efforts to sign a new left-back before the transfer window closes, with David Alaba and Nicolas Tagliafico emerging as targets.
The Citizens were hammered 5-2 by Leicester City in their second Premier League game of the season on Sunday, laying bare their defensive issues.
Pep Guardiola is said to be particularly concerned about the left side of his defence, where Benjamin Mendy has struggled for form and fitness since joining three years ago.
According to the Daily Mail, City have set their sights on Bayern Munich's versatile defender Alaba and Ajax ace Tagliafico.
Both players are 28 and fit the criteria recently laid out by chairman Khaldoon Al Mubarak, but the Premier League side have less than a week to agree a deal for one of the pair.
City have already added Nathan Ake to their backline this summer, while a £64m fee has been agreed for Benfica's Ruben Dias.
