The growing scandal surrounding allegations of historical child sex abuse has shocked the world of football.
Several accusations have been levelled against convicted child abuser Barry Bennell, who worked for Crewe, Manchester City, Stoke and junior teams in north-west England and the Midlands.
Allegations have also been made against other coaches.
Here is a timeline showing the key events and revelations so far:
