Saudi's assault on world tennis: 2,000 million and 90 days to respond. First was Formula 1, with its own Grand Prix and an offer to buy the World Championship.

Then football, with the creation of LIV Golf and the agreement with stars like Jon Rahm. And what's next? The tennis. Saudi Arabia has always wanted a Masters 1000 and if it ends up setting up its own circuit it will organize a tournament in winter, when the weather there is more acceptable.
