The Football Association has not yet received transcripts and footage in relation to an undercover newspaper investigation into alleged football corruption, delaying any potential probe into former England manager Sam Allardyce.
The City of London Police has opened a criminal case into a single suspected offence of bribery following the Daily Telegraph's investigation.
Allardyce has been informed he is not under police investigation, but may yet face action from English football's governing body.
"I was always confident… there was no evidence against me," Allardyce said in a statement on Friday. "I now ask that the Football Association deals with the matter as quickly as possible."
Allardyce has denied wrongdoing and it is understood the FA will only launch its own internal investigation when it has received evidence relating to all parties involved in the Daily Telegraph investigation.
Police have yet to disclose when the FA will receive all material in relation to Allardyce.
He left his position as England manager in September for "inappropriate conduct" after he was filmed allegedly discussing how to circumvent rules on player transfers while speaking to undercover reporters.
No arrests have been made by the City of London Police and it is understood detectives have also written to former QPR manager Jimmy Floyd Hasselbaink and informed him he is not part of their investigation, with no evidence to suggest he committed any wrongdoing.
