The France number one made a string of excellent stops in the second half and one was exceptional, as he denied Javier Hernandez from point-blank range.
Spurs dominated the first period in Germany but in the end had Lloris to thank for a result that keeps them second in Group E and only a point off the top with two home games to come.
"I think after two years here and a few months, my third season at Tottenham, only I can say good things for him," Pochettino said.
"He is a fantastic goalkeeper, one of the best in the world. Today in the second half he was brilliant again.
"I have not changed my opinion about him, that he is one of the best goalkeepers in the world, he showed in every action today he is top quality, one of the best.
"I think he is in the best moment of his career and always it is important to have a keeper like him."
