Police have launched a formal investigation into the football corruption allegations made by the Daily Telegraph in September.
The City of London Police said the probe had begun after reviewing information collected by the newspaper.
A statement read: “Detectives from the City of London Police Economic Crime Directorate have reviewed material gathered by a recent Daily Telegraph investigation into suspected corruption in football.
“This review of the material has concluded and the decision has been taken to begin a criminal investigation into a single suspected offence of bribery.”
There is no further information yet on which aspects the investigation will focus on, or which individuals will be involved.
Sam Allardyce left his post as England boss after the newspaper investigation claimed he offered advice on how to “get around” rules on player transfers.
However, a City of London police spokesperson said Allardyce “is not part of the investigation.”
In a statement, 62-year-old Allardyce said he welcomed the confirmation, adding: “I was always confident that this would be the case as there was no evidence against me. I now ask that the Football Association deals with this matter as quickly as possible.
“While I am sad that my tenure came to an end early, I am nonetheless proud to have been chosen to manage the England football team and hope that today’s confirmation from the police will give me the opportunity to move on.”
