World number one Novak Djokovic is through to Sunday's final of the Australian Open after a less-than-convincing face-off with defending Melbourne champion Stan Wawrinka. The match was one of twists and turns, with an uneven performance on both sides which had spectators wondering about the energy levels and health of Djokovic. The 27-year-old admitted in the post-match interview that the error-riddled game had sapped him of his energy after the third set, but said he still thought he had played well.
