Manchester City have reportedly been told it will cost them £50 million to sign Tottenham right-back Kyle Walker, after missing out on Dani Alves.
The Citizens were expected to land Alves having agreed personal terms with the former Juventus defender, only to see him join Paris Saint-German instead on Wednesday.
Walker, meanwhile, has been heavily linked with a move to the Etihad Stadium since the season drew to a close, but City's attempts to strike a deal with Spurs have proved unsuccessful thus far.
The north Londoners are willing to sell the England international, but only if their demands are met – leaving their Premier League rivals with a decision to make.
City boss Pep Guardiola is in dire need of reinforcements on the right side of defence after Pablo Zabaleta and Bacary Sagna were released at the end of their contracts in June.
