Two-time Grand Slam champion Lleyton Hewitt has announced that he intends to retire after competing in his 20th Australian Open next year.

The 33-year-old has been thinking about his future following his second-round exit to Benjamin Becker in Melbourne last week.

Hewitt has also revealed that he hopes to become Australian Davis Cup captain in the future.

"I've thought long and hard," The Guardian quotes Hewitt as saying. "I plan to play the Aussie Open next year and most likely finish then.

"Obviously for me the Davis Cup is something we've worked extremely hard to put ourselves in a position in the World Group where we have a genuine shot. I believe with the guys now we have a lot more options, a lot more depth.

"Personally I'll be looking towards the grass-court season and most likely finishing here in Melbourne, which for me would obviously be special to play 20 Australian Opens."

Hewitt has three career titles to his name.
