20, 19, 17...

It's been a great Australian open. Djokovic win's his 17th slam, Sofia Kenin wins her first and Serena still waits for the all time record... 

This tournament leaves us with loads of questions:

Will Federer win another slam?

Who is the GOAT and how many slams will the big three finish on?

Will Serena Williams equal and pass Margaret's Courts all time record?

Can Nick Kyrgios keep his head like he did, throughout the whole season?

Which of the next gen will be the first to win a slam? Will the next gen EVER win a slam?

And if all three of Federer, Nadal and Djokovic played their absolute best in the same tournament, who would win?
