This is Bobby 90, a four-part special podcast series from The Athletic to mark what would have been Sir Bobby Robson's 90th birthday. In this final episode of the series, Sir Bobby talks about his various battles with cancer and the establishing of the charitable foundation in his name.

As preparation for his final book, Sir Bobby looked back over his remarkable life-story with George Caulkin. Thanks to the generosity of Sir Bobby's family we are able to publish the recording of those conversations, featuring memories of his life as a miner's son, watching some of the greatest ever Newcastle United teams, and embarking on an incredible football career of his own.

We also hear the moving story of Sir Bobby's repeated bouts of cancer and how he came to launch his "last and greatest team", the Sir Bobby Robson Foundation.

The shows were written by Sir Bobby Robson and George Caulkin, mixed and edited by Ollie Bellwood.
