Manchester United have reportedly identified Tottenham Hotspur right-back Kyle Walker as a possible transfer target.
Signing a full-back is believed to be one of Louis van Gaal's priorities this summer, and the likes of Dani Alves and Nathaniel Clyne have been linked with United in recent months.
However, the Daily Mail claims that Walker is being monitored closely, despite having four years remaining on his current deal at White Hart Lane.
The England international returned from a nine-month injury absence in the latter stages of last year, and he has shown signs of his best form since earning his place back under Mauricio Pochettino.
Spurs are likely to demand close to £20m for Walker, and that price could force United to look elsewhere, with Alves set to become a free agent in the summer.
