The 22-year-old is set to move from Schalke to the north London outfit in July when the Germany international’s contract expires in the summer.
Ranked as one of the Bundesliga’s brightest prospects, Holtby insisted he had no hesitation about agreeing to join Tottenham.
“[Tottenham] are not a small club and have an insanely good manager,” Holtby said.
“I simply had to take the offer from Tottenham. New things don’t scare me, they excite me. In my opinion Tottenham is a
big club in Europe.
“Without Tottenham’s offer I would have signed at Schalke. I can only repeat that [club chief] Horst Heldt made a very good offer.
“I believe that I have a good relation to the fans, because I have always been authentic and honest. Now they can decide on their own how to react.”
Holtby could join Tottenham before the summer, with Schalke reportedly open to agreeing an early release for the playmaker.
