The women’s final is set: Serena Williams will face Naomi Osaka on Saturday. On The Tennis Podcast, David and Catherine discuss how both players got there.

Serena beat Anastasija Sevastova 6-3, 6-0. What made this such a formidable performance? David was struck by Serena's net game. Has she ever been forward more? And was it a pre-planned tactic or a mid-match adjustment?

Is there a difference between “needing” and “wanting” Grand Slam titles? Catherine wonders whether, with Olympia now in her life, Serena no longer “needs” to win the US Open….but she might just want it more than ever.

Naomi Osaka, meanwhile, saved all 13 break points to beat Madison Keys in straight sets. How did she turn the negative head-to-head record in her favour? There’s lots of talk about her improved movement and defence, as well as her loveable interviews.

How will Osaka handle the occasion in her first Grand Slam final? She idolises Serena. She also beat her in Miami this year. But this is a different Serena.

Looking ahead to the men’s semi-finals, there’s lots of excitement about the potential for epics. Will the matches deliver the goods? Catherine and David still have a feeling for Del Potro. But conditions are set to be less hot and humid. How much will that favour Djokovic?

There will be daily editions of The Tennis Podcast throughout the US Open fortnight.

The Tennis Podcast is produced in association with the Telegraph and sponsored by Amazon Prime Video, the new home of the US Open in the UK.
