Is it psychic ability or plain luck that I predicted Djokovic will be up 4-2 in the sixth game just after the fifth game finished. It was looking pretty tight so most would probably have thought it'd be on serve.
But now Federer looks angry.
17:45 - could we be seeing Djokovic 1-0
18:38 - As a Djokovic fan I just can't with this match, I'm suffering a heart attack.
