Video: Azarenka says she would like to have Roger Federer's serve

Despite becoming number 1 in the world and winning multiple Grand Slams, Victoria Azarenka still believes she could add more to improve her game.

The Belarusian revealed in an interview with the ATP Tour that if given the chance to borrow a shot from an ATP player, she would like to have Roger Federer's serve.

"Sometimes that it is a bit underestimated how good it is with the accuracy," said Azarenka. "Maybe not necessarily with power where there are other players who are dominating that area but the precision is.”

The two-time Grand Slam winner was eliminated by Ashleigh Barty in the round of 16 at the Western & Southern Open, but will look to rebound at the upcoming US Open.
