( CNN ) -- The man they call the `` Wizard of Ballydoyle '' has got a master apprentice . Irish champion trainer Aidan O'Brien has a reputation as a brilliant tutor of horses , but his most prized protege is now his eldest son , Joseph . The pair galloped into the history books last season as the first father and son -- in the role of trainer and jockey -- to win England 's Epsom Derby , one of the world 's most famous flat races , with Camelot . `` It works well , '' Joseph , who is his father 's first-choice jockey , told CNN 's Winning Post . `` We both discuss what way we 're going to ride the horse and it does n't always go to plan -- it usually does n't -- but when it does it is great . '' Joseph is lean , rosy-cheeked and softly-spoken -- and modest too . The 20-year-old rode his first winner , trained by his father , at Leopardstown in 2009 just days after his 16th birthday . Since then the O'Brien father-and-son combination has claimed high-profile victories in England , Ireland , the U.S. and Dubai on celebrated horses including Camelot and St Nicholas Abbey . `` I suppose Joseph has never known anything else since he was a baby , '' said O'Brien , surveying the Ballydoyle yard tucked away in the heart of the Irish countryside in County Tipperary . `` He probably knows how we think better than anybody . He knows when it goes wrong too -- he 's the first to admit it . '' O'Brien learnt his trade from his own father , a farmer and small-scale trainer in County Wexford , Ireland , before becoming a jockey , who dabbled in training on the side . The 44-year-old was Ireland 's amateur champion jockey but it was his knack of training horses that saw him snapped up by Coolmore , Ireland 's global breeding and training powerhouse , in 1995 . He has been Ireland 's champion trainer since 1998 and British champion trainer four times , guiding great horses such as Giant 's Causeway , Galileo and High Chapparal . With such a prestigious brand to protect , not to mention family honor , does O'Brien treat his son differently ? `` No , I do n't think so , '' answered O'Brien in a straightforward manner . `` He 's seen it all and heard it all good and bad . `` It 's obviously a much closer relationship as we all live together but it 's more or less the same . '' Joseph agrees that he is not treated any differently by his father to the other jockeys charged with riding potential winners home . `` There 's always a little bit of pressure , '' he explained . `` But I like pressure because when the pressure 's on it means you 'll be sensible . '' Dynasty in safe hands . The pressure just might increase on Joseph at some point in the future . As well as being his father 's favored jockey , O'Brien has named him as his potential successor . `` I 'd be delighted , '' said O'Brien . `` He 'd have to be finished riding at that stage but those things are a long way down the road . `` We 'll look forward to it when it does happen . '' At least Joseph does not have to worry about sustaining the O'Brien dynasty alone . The 20-year-old is the eldest of four children and O'Brien -- whose wife Anne-Marie was also a trainer -- already has them all riding out to exercise the horses . No wonder Ballydoyle has a reputation for breeding future stars of the turf -- and the training yard .
The rising star of champion trainer Aidan O'Brien 's stable is his own son Joseph . The pair are the first father-and-son to win the Epsom Derby as trainer and jockey . Joseph jokes their plans `` do n't always go to plan '' but the pair have had great success . O'Brien says Joseph could one day take over training at the prestigious Coolmore stable .
