My best wasn't good enough to beat Wawrinka - Novak Djokovic
Novak Djokovic congratulates Swiss eighth seed Stanislas Wawrinka for beating him 2-6 6-4 6-2 3-6 9-7 in an epic battle at the Australian Open to set up a semi-final against Tomas Berdych.
It was Djokovic's first defeat under the guidance of new coach Boris Becker, and brings to an end a winning streak of 28 matches on tour - and one of 25 matches over three years in Melbourne.
The Serb says he gave it his all, and it wasn't enough to beat Wawrinka - but says he is happy how life under his new coach has gone so far.
