The Belgium international has emerged as one of the best defenders in the Premier League since joining Spurs in 2015 and has forged a formidable partnership with compatriot Jan Vertonghen.
"I am trying to focus on the pitch, trying to help the team, give my quality on the field – that's important and the rest will come," the former Ajax defender told talkSPORT.
"I have my father and my agent who are sorting out that kind of thing.
"Me, I am here to play football, to win things with Spurs and to give my best for the team. I did that from day one and I will do it now as well."
Alderweireld has made 92 appearances for Spurs since joining from Atletico.
