Listen to @manutd defender @rioferdy5 speaking about former United manager Sir Alex Ferguson

The former Manchester United defender Rio Ferdinand has a new book out in time for Christmas, it's called two sides and explores everything from his early days to his playing career at Old Trafford. In the book he talks openly about his relationship with the former United boss Sir Alex Ferguson, and whilst speaking to the BBC's Nick Grimshaw, he talks about how the Scot showed two sides of his game- the anger and the compassion. #ManUtd #bbcrmsport
