These allegations -- which stem from just one of the 21 investigations being conducted by British regional police forces -- have come to light since last Thursday when London's police force the Metropolitan Police announced the launch of their enquiry.
Aside from the four unnamed London Premier League clubs -- the Met would not reveal who they were -- there are two Championship sides and three from League One and Two.
The rest are non-league, amateur or non-professional clubs according to the Met.
"The Met take all allegations seriously, and specialist officers will work through the information passed to them," said Detective Chief Superintendent Ivan Balhatchet of the Sexual Offence, Exploitation and Child Abuse Command.
"The number of referrals, pieces of information and allegations will change. Officers will continue to work through the information that has been reported.
"The Met will not be giving a commentary as this investigation develops and is not discussing the names of the clubs involved, or number of allegations against each club."
