The 23-year-old midfielder moved to Craven Cottage on a short-term deal until the end of the season in a bid to help Fulham avoid Premier League relegation.
I loved playing for Tottenham and I would like to fulfil my contract there
Holtby has since scored one goal and made three assists for the west London club after struggling to hold down a starting spot at Spurs.
But the Germany international is expecting to return to White Hart Lane in the summer.
“There is little sense in talking about other clubs since I have a long-term contract at Tottenham,” Holtby told Goal.
“The status quo is that I will go back to Spurs after the summer holidays. I can’t tell you what is going to happen until then. My agent takes care of everything and as far as I know his mobile is always turned on.
“I loved playing for Tottenham and I would like to fulfil my contract there. But at first it is important to avoid relegation with Fulham.
“Alone because of these unbelievable fans. I would be a shame if such a great club would not play in the top league.
“I will only think about stuff when the time comes to think about it.”
