What a fitting end to another fine year! Is this finally the time when the Next Gen break through?
I know, I know, we've asked this every year since about the year 20-something. But this feels different, doesn't it? Let's see what happens in 2020...
The season isn't completely over though... we have the not-so small matter of the inaugural Davis Cup finals in Madrid next week.
Andy Murray says the new format, which has been criticised by the likes of Roger Federer, Alexander Zverev and countless fans, should be given a chance. Who are we to argue with a Knight of the Realm?
if you return to the website/app tomorrow you will find an explainer piece on the new tournament which features 18 national teams including Great Britain.
And if you need a tennis fix tonight then head over here to have a go at our 'Who said what in 2019 quiz'.
Anything else? Nope, that's it. Thanks for your company on a thrilling ATP Finals weekend - and make sure join us in Madrid later this week! Hasta luego...
