The Australian Open is four days old - and here are the big questions for the pod:

- Just how well did Emma Raducanu play with half her game wiped out by a blister on her right hand?
- What have we learned about the US Open champion during her first senior Australian swing?
- How open is the bottom half of the draw?
- Can Simona Halep take advantage?

- Who is the biggest shock exit so far?
- What can Andy Murray realistically expect to achieve if he is losing in the second round of that draw?
- Is Nick Kyrgios going bald?!
