I missed the presentations - sounds like they were more interesting than the matches 
I also get slightly worried when they start driving cars around the court - I remember Iga getting into a car and driving it round the court at quite a speed! (I was hoping that she'd passed her test!)
Loads of people have been playing tribute to Rafa on Instagram - a lot of the young players saying how much he'd inspired them, even a nice one from Foggy (although he did have a bit of a dig by saying thank you for letting him win a few times)
I think the most random one I saw was from Noel Fielding - I didn't realise he was such a Rafa fan!
