Alderweireld was only brought to Spurs from Atletico Madrid last summer, but he has quickly had an important role to play at White Hart Lane.
The Belgian defender has been a mainstay in the side this season - alongside both Kevin Wimmer and Jan Vertonghen - and he has helped Spurs keep the best defensive record of any club in England’s top flight.
There have been suggestions that Alderweireld should have been placed on the shortlist for the PFA Player of the Year award.
But Pochettino said: “His performance has been fantastic from the beginning of the season and he doesn’t need to be recognised to feel that.
“Football is about scoring goals but, as a manager, the keeper and defensive line are at the same level of importance.”
Tottenham’s impressive defensive record has been one of the major reasons behind their push for the Premier League title.
Spurs have conceded just 25 times in their 33 Premier League matches to date, and Alderweireld has started in every one of those games.
The 27-year-old will now be looking to keep up his impressive form, with Tottenham’s next match coming against Stoke City at the Britannia Stadium on Monday evening.
