Novak Djokovic left Sky Sports commentators utterly stunned with the manner in which he secured a crucial point during his Shanghai Masters win over Zizou Bergs.
Having claimed the opening set 6-3, the second proved a much tighter affair as Djokovic battled relentlessly to wrap up a 7-5 victory, sealing his place in the semi-final.
But it was during that second set that Djokovic demonstrated precisely why he remains such a formidable force on the global stage. He displayed remarkable resilience and tenacity while under pressure to keep the ball alive repeatedly on his way to eventual victory during a breathless point in the second set.

Bergs delivered a perfectly placed serve towards Djokovic's right side, before hammering the return shot across the entire width of the court to his left.
The Serbian scrambled desperately to reach the ball, managing only to lob it high into the air to ensure it remained in play, reports the Express.
This scenario unfolded four additional times as Bergs selected his power shots at will - each time the Serb guessing correctly which side to move to successfully return the ball - before Djokovic crouched low on the next attempt to drive the ball forward with greater momentum.
The surprise tactic ultimately proved successful, with Bergs subsequently sending the ball sailing beyond the court boundaries to hand Djokovic the point.
The Sky Sports commentary panel were left bewildered by the spectacle they had just witnessed, expressing their amazement at the persistence and skill of the 38--year-old Djokovic.

One commentator exclaimed: "Oh no, no, no, no, no, no. Five, five overheads in a row or high balls that Zizou plays and he just cannot break down Djokovic. Who can?!"
His fellow commentator then chimed in: "I'm not sure I've ever seen a point like it. Bergs really struggling with the overheads and Djokovic, well he's so experienced and just knew to keep putting the ball up there, high into the Shanghai night.
"Ultimately, Bergs, he just couldn't keep it going any longer. Very hard to recover from losing that point."
Stunned by what he had just witnessed, the original commentator then exclaimed: "Five, five times he kept putting up the high defensive ball. I mean, that's unheard of."
Following his victory, Djokovic has advanced to the semi-finals of the Shanghai Masters, where he will face Valentin Vacherot. The pair will battle for their place in the final on Saturday, October 11.
