I wouldn't want to have been one of the spectators who paid top dollar to view that (as I'm sure many of you who have gone to a finals match of the AO know, the tickets aren't cheap).
I was thinking this the whole time, feel for Chung foremost, but feel also for the fans who paid for a seat expecting something on the level of Djokovic v Federer (which was a possibility, nay, probability, a week ago) and got this instead. Complete schooling
Cilic v Federer should be a decent match. It will be interesting though, as Cilic has just gotten through two matches against two opponents who weren't 100% (granted, one of them was Nadal), and Federer has just had a breeze of a semi-final after breezing through all his earlier matches anyway. Neither got truly tested in their semis, Federer arguably hasn't been tested at all, and although Cilic has had one five setter this tournament, the latter sets of that match weren't against a competitive Nadal. They'll both be, by a pretty large margin, the biggest test the other has faced.
This said, predicting Federer in four sets (four, purely because I want a somwhat-decent final to make up for the lacklustre semis)
