One of the year’s great sporting occasions will be made even more memorable if Frankie Dettori can win the Epsom Derby at the 15th attempt. The popular pint-size Italian rides Authorized (the biggest Derby favourite in a decade) in Saturday’s race.

But Frankie’s quest is just one of many stories BBC Sport will cover during our two days at Epsom. As well as the top-quality racing - don’t forget Friday’s Oaks – our team will bring you all the atmosphere from one of the biggest race meetings of the year.

Certainly I have very particular memories of Derby Day. The first time I went – back in 2003 - I was overwhelmed by the colour, the grandeur and the sheer number of people. The memories come rushing back - the sea of open top buses and stretch limos in the middle of the course, the track undulating across the Downs and the realisation that I had, by far, the cheapest suit of any of the thousands of spectators who had come to soak up the occasion, as well as the sun.

The final edition of Inside Sport is a very special one.

Our cameras have been filming with one of Britain's best and most controversial referees, Graham Poll, for the last year. Ever since, in fact, he made his three yellow cards mistake at the World Cup Finals. It's a revealing portrait of the life of a Premiership referee and you will see, in real time, Graham Poll's comments on the many controversies that have followed him around in what turned out to be his final season.

I'll be very interested to know what you make of it. I have seen an unfinished version and I think - love him or hate him - it's a very compelling watch.
