Mauricio Pochettino already considers Davinson Sanchez one of the best centre-backs in the Premier League — but believes he will go on to become the best in the world.
Tottenham's manager has been stunned by the 21-year-old's speedy adaptation to English football after a club-record £42million move from Ajax in August.
The Colombian has taken no time to establish himself in the Spurs backline, most prominently in the middle of a back three, with Toby Alderweireld and Jan Vertonghen either side.
But Pochettino insists there is much more to come.
