BBC's World Football on age cheating

BBC World Service's World Football programme looks at the ongoing problem of age cheating in African football.

Alan Green talks to Tim Cole a professor of medical statistics at University College London about the MRI scans used to determine the age of players at international youth football tournaments.

Former Nigeria international Jonathan Akpoborie also gives his views on the problem, following the exclusion of nine players from the 2013 African Under-17 Championship in Morcco after they failed MRI scans on their wrists.
