Wanyama, who last week joined Spurs from Southampton, played with Alderweireld for the Saints during the 2014/15 season and the Belgium admits he is a massive fan of the Kenyan.
"Obviously I played with him at Southampton and I think he's one of the best midfield players in the Premier League," Alderweireld told the club's official website.
"He's strong, he can play with the ball and mentally he's very strong too.
"He likes to work hard and that's perfect for the team that we are building now."
Alderweireld added: "This year we will play a lot of games at the highest level – in the Champions League.
"Victor is strong and he has a lot of experience, having played in the Premier League and the Champions League before. He knows what you have to do and what's asked of you at that level.
"I feel he will bring us even more strength and power in midfield but he's also good on the ball which will be great for us because we like to build from the back.
"As a person he's so nice, too. He's good for everybody and the fans will know that quite quickly. He's a beast on the pitch but a very nice person off it."
