Stan Wawrinka has one of the nicest and most effective one-handed backhands on tour. Simona Halep was trying to master this particular shot during her training, and she posted a video on twitter asking the opinion of the Swiss.

What Wawrinka said about Halep’s one-handed backhand

Stan couldn’t refrain from answering, and this was his reply:

“Love it! Great technique. Missing a bit of spin

! But footwork much better than mine.

Will Simona change her backhand?
