The White Hart Lane boss was speaking ahead of the New Year's Day clash with Watford.
And the Spurs supremo very much poured cold water on any hopes the Bundesliga side might have of bringing Wimmer back to Germany.
"No, we are not talking about that internally," Pochettino said when questioned about Wimmer heading back to his old club on loan, according to Talksport.
"I am still very happy with him, he is still very young.

"When he brought him he was not only for the present but for the future.
"I don't expect that players will leave the squad in January, it makes no sense."
The Austrian defender has had a frustrating second season at White Hart Lane, having impressed when deputising for Jan Vertonghen in an extended spell in the spring of 2016.
Wimmer played ten consecutive Premier League matches, starting in January, when his Belgian teammate suffered a knee injury. It was a run that saw Spurs gain momentum in their title ambitions, losing just once during that time and securing seven wins.
He subsequently signed a new five-year contract in July, hinting at Mauricio Pochettino's confidence in the player.

But this campaign has failed to provide the 24-year-old with the game he would have been hoping for, especially considering Toby Alderweireld was injured for an extended period.
Victor Wanyama's signing this summer has had an unpredicted effect on Wimmer's first team chances, with it allowing Eric Dier to deputise in central defence whenever necessary.
Youngster Cameron Carter-Vickers has even made the bench ahead of him for several fixtures, meaning Wimmer has made just five appearances for Tottenham, two of which came in the Premier League. He netted an own goal at centre back during the 1-1 draw with Arsenal at the Emirates in November, and was then drafted to fill in at left back for an unfortunate defeat away to Chelsea.
Get German Football News had suggested a loan return to Western Germany was close, a prediction that led to Pochettino being questioned about the player. However, if the Spurs boss is to be believed, it appears such links are some way off.
Wimmer could come in for Jan Vertonghen against the Hornets on Sunday, with Jan Vertonghen suspended for the clash.
