This was always a match with barely any footage, very sparse on highlights, and since I didn't see it live, I'm gonna give this a go....
But this is one Federer loss I could take no joy from (not that I do much anymore, anyway. I enjoy the old man still schooling youngsters).
I don't like Millman touching a slam QF stage for one, Federer wouldn't have won the tournament anyway, and Djokovic wasn't made to work for it much (a sadly recurring happening in the 18-19 slams for him), as we were denied a Djokovic-Federer clash. So really not my prefered outcome at all.
