The event gets underway on Monday afternoon with some of the world’s best stars eyeing to take Nadal’s crown in the Spanish capital.
Madrid has hosted an international tennis tournament annually since 2002.
But the future of the Open is under threat, with no plans to host the tournament beyond 2021 currently agreed.
The Local government may decide to stop hosting the event, which was attended by 260,000 people last year.
And Nadal has done little to persuade the authorities to continue with the competition he has won five times during his career.
“I think the town hall will have to make that decision,” he told reporters.
“It’s not ours to make.
“It will be the town hall who will decide if they want to continue to bet for a tournament of this size or if they prefer to invest in something else, or if they don’t prefer to bet on a sport like this.”
But Nadal did go on to praise the tournament, claiming Spain’s love for tennis makes the event a success.
“I think we have a great tournament here in Spain, one of the highest levels, a really high-level tournament,” he continued.
“It’s true that it’s also one of the sports that there are a lot of people watching us.
“It’s very difficult to be able to achieve a tournament like this one here because there are a limited number of them.”
