Boris Becker's commentary is hilarious.
"Wow, Andy is so fit right now."
"If you let your head drop, Djokovic will give you such a pounding!"
"New balls! Das is good news for Andy!"
"You don't want to be on the receiving end of Novak!"
OK, he may not have actually said any of that stuff, but it wasn't far off. I hope they keep him.
