Unfortunately I couldn't watch this one. From the sounds of it, it was high quality. Andy was obviously not at his best, otherwise he wouldn't have lost to this Djokovic
This Djokovic =/= 2016 2nd half Djokovic!
I recommend you to rewatch the match, just to recalibrate your expectations about AO. That court plays fairly slower, and if Murray couldn't win here in Bo3 (where he supposedly had all the advantage: faster court, coming with confidence into the final etc.), he'll given the extra task to do it in Bo5.
As said, he should invent some new tactics, because his usual one isn't working against Novak.
