Most complete tennis player of all time? (ATP and WTA)?

Hmm.. very excellent questions. For the men I would probably say Jimmy Connors. He had a great serve, great return, could finish the point at net with a volley, but could also be consistent from the baseline when need be. However, on the women's side I am going to to with Martina Hingis. Here's why, she was fantastic at moving the ball around the court and had a great geometric understanding of the court. Also the was a solid server and solid returner. She also could finish points at net due to her doubles play. She could also out hit anyone from the back of the court. Also she is one of the only women to have a winning record against every single top 10 woman from her generation. In my opinion these two players Jimmy Connors and Martina Hingis are the most complete players.
