Pat Cash needs little introduction...He is a Wimbledon Champion, the youngest person ever to win the Davis Cup Singles title and a household name in Australian sport.

Pat first came to the tennis world's attention as a junior player in the early 1980s. He was ranked the top junior player in the world in 1981, and in 1982 he won the junior titles at both Wimbledon and the US Open.

Pat's greatest tennis achievement was winning the men's singles at Wimbledon in 1987. After defeating world No.1 Ivan Lendl in straight sets, he climbed into the stands to celebrate with his family and coach- a practice which has since become tradition among Wimbledon winners. He went on to twice make the final of the Australian Open – in 1987 and 1988 – but lost five-setters on both occasions, to Stefan Edberg and Mats Wilander respectively.

A regular Davis Cup representative for Australia, Pat was part of Australia's winning teams at Kooyong in 1983 and 1986. Cash first represented Australia as a 17-year-old and finished with a 31-10 Davis Cup record over eight years.

Nowadays, Pat still plays a large part in the Tennis world; he hosts CNN's tennis-focused magazine show Open Court, he is a regular colour commentator and he also runs the Pat Cash Tennis Academy. He has won the over-45's Wimbledon doubles title with fellow Aussie Mark Woodforde in 2010, 2011 and 2012. Pat has now collected the Junior, Tour and Legends Wimbledon titles. To date, he remains the only person to have done so.

Steve: What do you do to keep fit these days and what is your diet like?

Pat: Well, at the moment I'm rehabbing from knee surgery again. I have been in great shape for many years now but I had an incident on a Swiss ball and twisted my knee which required surgery. I have been told by the surgeon that he sees many knees from straight people like me doing straight leg twists holding a Swiss ball between the legs. Crazy after all the tennis I've played to have some stupid thing like this happen. My diet is pretty much wheat free and has been for 10 years now, though I'm not as strict as I used to be. I do like a dessert and a packet of chips

Steve: You won the over-45's Wimbledon doubles title with Mark Woodforde in 2010, 2011 and 2012. How competitive is that competition and how much tennis do you still play throughout the year?

Pat: The Grand Slam doubles aren't as serious as they used to be that's for sure and having a partner like Mark makes life pretty easy. I play a combination of singles and doubles exhibitions, but more singles generally. A usual year will have me playing 12 -16 events a year. Some are 1 night or day other 4 or 5 days. That's pretty demanding especially when you play guys much younger. This keeps me working hard off court which I love.

Steve: You have won a lot of big tennis accolades. What has been the highlight of your career? Winning Wimbledon?

Pat: Wimbledon and Davis Cup for Australia they were the 2 things I wanted to do and I did them in the few years I was fully fit back in the mid - late 80's

Steve: Your son Jett is 18 and has done very well through his junior career. How is his form at the moment? Are we going to see him at the Aus Open over the next few years?

Pat: Jett wants to go to a US college. He is a smart kid and wants to study chemical engineering or biology and continue to play tennis. Perhaps he will play the tour after that but it's up to him.

Steve: You've done a lot of work with junior tennis players in recent years, taking the Junior Australian Davis Cup team to Mexico this year. Which up-and-comer are you most excited about?

Pat: We have a very good bunch of kids coming through so any of them could make it. Australian tennis hasn't had a great record in recent years bringing top juniors through but it's very hard work out there as tennis is the toughest sport in the world to break through from juniors to tour player. There are thousands of kids on the junior circuit.

Steve: What do you think it takes to be an elite tennis player in the modern game?

Pat: Much the same as it has always been. Lots and lots of hard work, attention to detail, great physical ability and some luck

Steve: You struggled with injuries to your achilles tendon, knees and back later in your career. Were there any particularly bad injuries you endured in your career?

Pat: All injuries are bad. I recovered from all of them 100% except the achilles. At the time of the achilles rupture I was not in the right frame of mind to rehab properly and therefore it didn't recover like it should of. I learned my lesson the tough way.

Steve: What are your views on the evolvement of tennis racquets and other new technologies coming into the game such as Hawk-Eye?

Pat: I love Hawkeye technology as it has improved the game I'm not sure about string technology as its made the average player good and reduces the skill level necessary for a player. For example to hit a topspin lob or good return all you need to do is make some contact on the ball and lots of spin comes off the string on to the ball, thats not skill it's just technology. Is point after point of big serves and hard forehands really that interesting? I don't think so.

Steve: If you could make any changes to the modern game of tennis, what would they be?

Pat: Get rid of the let rule and limit string and racket technology

Steve: In your opinion, who is the best tennis player you have played against, and who is the best tennis player of all time?

Pat: Becker McEnroe Lendl Wilander Edberg all had certain shots that were the best I have played against. Best of all time is a fun but mainly pointless conversation unless you know history and the game very well. Read the blog on my website where I go into detail.

Steve: Who do you think will be the top player in 2013 and/or the most improved?

Pat: Hmmm... It's hard to say as the top 4 have all had great years recently but I tend to think Murray will continue and win more Grand Slams.

Steve: What do you think the future holds for Bernard Tomic? Do you think he's got the maturity/ self-discipline to become a top 10 tennis player?

Pat: Not at this stage but he's still young enough to turn things around.
