#2 Nick Kyrgios vs Stanislas Wawrinka
When it can happen - 4th Round
Things aren't particularly rosy between these two. The feud began when Kyrgios infamously sledged Wawrinka about his girlfriend in their round of 32 match in Montreal in 2015.
They were reportedly later involved in a locker room scuffle, where Wawrinka is believed to have grabbed Kyrgios and dished out a bunch of abusive words. While they may have pretended to have forgotten the incident when asked about it in press, things will possibly never be the same between them.
Should these two make it to the 4th round, it'll be a match that no one would want to miss watching. With the vociferous Aussie crowd sure to be on the Australian's side, there will be a lot more at stake than just an Australian Open quarter-final spot.
