In Episode 42, we celebrate our first birthday with an interview with Serena Williams. The World No.1 tells us what is driving her to continue into her 30's, whether she ever feels aches and pains in the morning, and how driven she is to overtake Chris Evert and Martina Navratilova in the history books.

We also preview the French Open, dissecting the draw of the second Grand Slam tournament of 2013.

In the first part of our in-depth, exclusive interview with the great coach Bob Brett, the Australian tells us all about the three and a half years that he spent coaching Boris Becker between 1987 and 1991. He explains how he tried to get the best out of Becker at a time when Ion Tiriac didn't think Brett was the the right man for the job, how he risked the wrath of Boris by telling some home-truths in a rain-break, and how emotion overcame him when Becker reached No.1 in the world.

Brett starts by telling us about the legendary Australian Open Davis Cup captain Harry Hopman, who was Brett's mentor.

Before all of that, Catherine and David continue to argue about who will win the French Open, and reflect on Rome.

In Episode 40, we feature an exclusive, in-depth, emotional interview with the long-time coach of Tim Henman - David Felgate. What was it like when Henman went from spindly 17-year-old outsider to Wimbledon semifinal Top 5 contender? How tough was it when the relationship came to an end after almost nine years? And how did Felgate deal with watching, from the BBC Radio 5 Live commentary box, as Henman so nearly reached the final of Wimbledon in 2001? All of that, and a full review of Madrid, where Rafa's good form continued, but it wasn't enough to win over Catherine.

We are into the fifth month of the year, and David is already nominating someone for player of the year  so far - here's a clue, he's not in the Top 4. We also meet the youngest woman in the Top 100 - Donna Vekic - and talk to her coach, David Felgate.
