The Germany international moved to White Hart Lane from Schalke in January 2013, but failed to hold down a regular starting spot under Andre Villas-Boas and then Tim Sherwood.
The 23-year-old was loaned out to Fulham for the second half of last season, having made just six league starts for Spurs in 2013-14, but Holtby failed to save the Craven Cottage outfit from relegation.
"Lewis is optimistic about the future at Spurs," he told Sky Sports News.
"There is a new manager there now which means it's a fresh start for him and a fresh start for everyone.
"He is happy at Tottenham and has a good feeling there.
"He wants to stay and prove himself and be part of the team."
