Tottenham boss Mauricio Pochettino is facing a battle to keep his squad together this summer.
The London Evening Standard says Kyle Walker has sought talks with Pochettino over his future.
But he isn't the only senior player weighing up his options.
Danny Rose has also spoken to Pochettino about the interest in him elsewhere.
Toby Alderweireld has, meanwhile, demanded pay parity — at the least — with top earners Hugo Lloris and Harry Kane, who collect £100,000 per week. Alderweireld is another who has been made aware that he could earn far more than his £50,000-a-week salary at another club.
