Spurs lost 2-1 to Monaco at Wembley in their Champions League opener a fortnight ago.
Alderweireld said: “It's about learning from your mistakes. We've got quite a young squad, so sometimes it does not go the way we want. We need to bounce back and come back better and our ambition is to do that.
“It's a difficult one but we have to get a good result in Moscow to get into the next round. Even the Wembley game, the second half was better and that's the way we have to play. Unfortunately we lost, and that puts the pressure on. Sometimes it happens. Now we need to be ready and get a good result."
