Alderweireld remained at the club over the summer, despite reported interest from Manchester United, Bayern Munich and Paris Saint-Germain, and he has reintegrated into Pochettino's squad, starting the last three games.
Pochettino said: "Look, when in England the transfer window closed and in Europe closed I think we move on.
"Then like always I told you, I never talk about situations, that maybe yes or maybe no, the club is dealing or working. In that situation it's not my job to talk about individual situations.
"I think it's so clear, not only in his case, in all the players that have different situations, we are so clear, the club is so clear, when something happens we are going to communicate the news as soon as possible.
"I am not going to talk about individual things. It's not going to help anyone."
