Andy Murray's monumental fourth round loss to underdog Mischa Zverev left fans and commentators shell-shocked.
Zverev put on an absolute clinic at Rod Laver Arena, blasting his opponent off the court in four sets 7-5 5-7 6-2 6-4.
The world No. 1 had no answers to the incredible performance, particularly at the net on the volley, dropping the game 7-5 5-7 6-2 6-4.
Murray's form was slammed by Jim Courier, calling his stroke play "atrocious" as he dropped critical points to his opponent.
Fans joined the fray on Twitter, unafraid of holding back on the recently-knighted 29-year-old.
