Day 4 was a day of upsets in Melbourne. No. 3 Agnieszka Radwanska got blitzed by Mirjana Lucic-Baroni (as Courtney flagged), but the biggest story was six-time Australian Open champion Novak Djokovic stunningly falling in five sets to 117th-ranked wildcard Denis Istomin.

To assess Novak's slide, as well as other perceptions of him in Serbia and the wider world, Ben chats with Belgrade-based Saša Ozmo, a journalist for Sport Klub Srbija. How did this slide start for Novak, and what are reasonable expectations for him going forward?
