Alderweireld, who signed a new long-term contract with Spurs last month, said the mood in the squad was "positive" - despite a run of poor form which has seen last year's Champions League finalists win just once in their last five Premier League games.
"For me, it's nothing like that," the Belgian said.
"If it was like this, I wouldn't sign a new deal. Now, for me, it's all positive.
"I think we've been so consistent for the last four or five years, so it's a little bit human to drop a little bit.
"Not that you want to drop. But sometimes it doesn't go your way and we have to find a way to get back to our level.
"On the other hand, I think we are [joint] fifth now so we're not doing so bad. It's the next step that this club has taken whereby if you are fifth everyone is not happy, so that's positive as well.
"Let me say so again: no negativity. I don't know where that's come from. Maybe there's a player that's not happy and maybe he wants to say something?
"It's all possible, but from 99 percent I'm telling you we're happy with the group."
