The 24-year-old joined Atletico from Ajax in the summer, but he is yet to make his competitive debut for Diego Simeone's side.
"It's true I've not played a minute but I have a good relationship with the coach," he told AS.
"I'm training well so we'll see what happens. Simeone has told me I'll get my opportunity and that makes me worry less.
"We have a good group of players here and I've had no problem adapting to things. Besides, as you know, I get along really well with [Thibaut] Courtois, who I also link up with for Belgium."
Alderweireld is currently on international duty with Belgium.
