The film tells the unlikely life story of Charlton, who, after winning the World Cup for England as a player, went on to become an Irish hero after leading their national team to their first World Cup as a manager.
Such successes are told against the background of the final year of his life stricken with dementia.
Charlton’s family, including his wife Pat and son John, are among the contributors.

The team of eleven includes: John Barnes, David Seaman, Robbie Fowler, Mark Wright, Matthew Le Tissier, Chris Waddle, Rob Lee, Ray Parlour, Lee Sharpe,Mark Chamberlain, Paul Merson, and Razor Ruddock. They’ll be trying to prove that it’s never too late to get fit.
