Stats - Djokovic can no longer return Sinner's serve

Novak Djokovic doesn't really seem to have what it takes to trouble Jannik Sinner anymore, especially when it comes to returning serve.

Known for his outstanding return quality, the Serb has failed to break the Italian once this season.

What's more, he hasn't had a single break point against the current world number 1 (in 6 sets played).
