Reilly Opelka says that Novak Djokovic is 'impossible to break,’ and his new and improved serve has just added to the nightmare.
Djokovic has made notable strides in improving his serve this season, adjusting his technique to put less pressure on his previously-injured elbow and finding a lot of extra speed in the process.
Opelka, though, believes Djokovic’s serve is still the last of your worries when you face the Serb, because the rest of his game is just so good.
"I think it’s more so because of everything else in his game," Opelka told ATPTour.com when asked if Djokovic’s new serve is what makes him so tough to play.
"He does serve very well. But he’s breaking serve more than 30 percent of the time, which is ridiculous.
"Obviously when you give him the first strike of the ball, it’s going to be even higher.
"He does serve well and it’s not talked about [as much as it should be], but it’s really the rest of his game that makes him impossible to break."
It should be noted, however, that Opelka is yet to actually play Djokovic in an ATP Tour match.
