Pep Guardiola is growing frustrated over Manchester City's pursuit of Tottenham defender Kyle 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.
City set out their intentions for the summer with the £43m signing of Bernardo Silva from Monaco followed by the £34.7m arrival of Ederson from Benfica.
