Manchester City are struggling to get a deal done for Tottenham fullback Kyle Walker.
The Daily Mail says City boss Pep Guardiola is growing frustrated over the pursuit of Walker.
The clubs have opened discussions about the England international but are still some £10million apart in their valuations.
City have proposed an offer of around £40million for Guardiola's main target while Tottenham want closer to £50m.
Walker has long been Guardiola's first option for right-back and the Spanish tactician was hopeful of getting players in place quickly ahead of a return to pre-season.
