Tottenham are on the hunt to secure a long term replacement for captain Hugo Lloris.
The French veteran has been at the club since arriving from Lyon in 2012.
However, football.london claims that as Lloris is entering the last stages of his career, Spurs are planning for the future.
Valencia goalkeeper Giorgi Mamardashvili, Brentford's David Raya, Brighton stopper Robert Sanchez and AC Milan's Mike Maignan are all targets.
The club are also being linked to Leeds United's Ilan Meslier, should the Whites get relegated.
Aston Villa's World-Cup-winner Emiliano Martinez is another who has admirers and would be available in the summer.
