Roy Keane has claimed the off-field issues facing Kyle Walker explain the defender's decline this season.
Walker, 34, has been one of the best full backs in the Premier League over the past decade, with the right back shining for Tottenham and Manchester City.
During his time at the Etihad, Walker, who has also won 93 caps for England, has lifted 17 trophies, including six Premier League titles.
However, the 34-year-old has endured an extremely difficult campaign - which has come amid City's wider struggles - and Pep Guardiola revealed last week that Walker has asked to 'explore options to play abroad', with both Milan clubs emerging as strong contenders for his signature.
