About 350 victims have reported child sexual abuse within UK football clubs, police chiefs have said.
The National Police Chiefs' Council said a "significant number of calls" were made to forces after several former players made allegations of abuse against coaches.
Its figures are based on information about existing investigations as well as referrals from a new NSPCC helpline.
The charity said the hotline has received 860 calls in its first week.
Within the first three days of it launching, the organisation made more than 60 referrals to a range of agencies across the UK.
That was more than three times as many referrals as in the first three days of the Jimmy Savile scandal, the charity added.
The phone line is available 24 hours a day on 0800 023 2642.
The Football Association has announced an internal review and a number of football clubs are conducting their own inquiries.
