Match-fixing in sport. It is a subject that makes fans boil with anger and ask: just how and why would any professional do it? Aren't they already paid enough for a job many of us would love to do?

In the This is Moneyball season 3 opener, assistant editor Lee Boyce and broadcaster Georgie Frost tackle this tricky subject and are joined by someone who was swept up in the madness.

Centre-back Moses Swaibu – a former Crystal Palace youth player – became one of the first names on the team sheet for Lincoln City in the late-2000s.

However, he became embroiled in match-fixing as he slipped down to semi-professional level.

For the first time, Moses candidly tells his story, how it unfolded, his regret and why a stint in jail helped him realise that he needed to make sure young players aren't tempted to make the same mistakes.
