Ancelotti is excited to get started as Real Madrid aim to defend their LaLiga Santander title.
"We feel good and are excited to start this new league campaign," the coach said.
"Every match will be very competitive and difficult, starting with tomorrow's one. It'll be a long season."
The 30-man shortlist for the 2022 Ballon d'Or was also a talking point at the press conference. Six Real Madrid players have been listed - Thibaut Courtois, Karim Benzema, Vinicius, Casemiro, Luka Modric and Antonio Rudiger - but Toni Kroos was left out and the coach was asked about this.
"That surprises me, because he had a good season," he replied.
"I'm also surprised that they left out the likes of Fede Valverde, Eder Militao and David Alaba.
"I suppose they can't list all the Real Madrid players, as that would be a big problem."
On Courtois and his chances of winning, Ancelotti stated that the Belgian is the best goalkeeper in the world right now.
"We're enjoying Courtois, the best goalkeeper in the world right now," Ancelotti said.
"I can't say if he's the best I've ever had, as I also worked with goalkeepers like [Gianluigi] Buffon, [Petr] Cech, [Manuel] Neuer, [Iker] Casillas and Diego Lopez."
