Cahill remembers the 12-year-old that turned up at his door 'dressed in Agassi gear' and says that he was already a pro, even at that age. Memories of Hewitt's greatest achievements are discussed, what he was like to coach, and what Cahill thinks we can expect of Hewitt the coach.Craig Willis, the Australian Open's on-court announcer, is another special guest, as is Great Britain doubles player Colin Fleming, who lets us know what Andy Murray is in for in trying to be a tennis playing father.  See acast.com/privacy for privacy and opt-out information.
