Zinedine Zidane has agreed a new deal to remain Real Madrid head coach until 2020.
The Frenchman, who has led the Spanish giants to back-to-back Champions League titles, will double his salary at the Santiago Bernabeu to €8m (£7.3m) per year, according to AS.
The 45-year-old is the fourth-most successful coach in Real Madrid's history with six major title wins, including one La Liga title and two Uefa Super Cups.
He took over as Real coach in January 2016 on a two-and-a-half-year deal following the dismissal of Rafael Benitez.
"Some day that will end but my relationship with Real Madrid does not depend on contracts or money.
"I am happy with the faith the club has shown me and I'm pleased with the work my players put in. I could sign for 20 years but I know where I am and what my aims are.
"Who knows, maybe within a year I won't be here and that's that."
Real face Barcelona in the first leg of the Spanish Super Cup at the Nou Camp on 13 August, with Zidane revealing that Cristiano Ronaldo was ready to play despite returning to pre-season training only recently.
"He is ready and doing well. He trained a lot physically on holiday and is ready," the Frenchman said.
Zidane also spoke about the world-record transfer of Neymar to Paris Saint-Germain and warned that Barcelona would still be a dangerous opponent even without the mercurial Brazilian.
"They won't be the same as Neymar because he is incredible, but they will certainly give their all," he said.
"There are not many players like Neymar. You cannot simply replace him but whoever steps in, I'm certain they will bring something special."
