The League Managers Association (LMA) has demanded the Daily Telegraph publish every detail of its investigation into corruption in professional football.

Already the revelations have seen Sam Allardyce step down as the England manager over his comments regarding third-party ownership of players to undercover reporters. There have also been allegations about coaches accepting “bungs”.

Tommy Wright, the assistant manager of Barnsley has been fired by the Championship club after being filmed allegedly accepting a £5,000 cash payment from undercover reporters. He has denied any wrongdoing.

The LMA said in a statement: “Following further revelations by the Telegraph and a follow-up LMA meeting with the FA this morning, the LMA remains extremely concerned about allegations made against a number of managers and individuals in the game.

“Alongside the FA, and the other principal stakeholders in the game, we want to fully investigate any and all substantive allegations of corruption, quickly and comprehensively. Very disappointingly, this process is being delayed as the Telegraph is yet to provide to the FA, as requested, full and complete unconditional disclosure of all the information it has.

“We urge the Telegraph to provide full disclosure of all its information relating to the allegations, including all recordings, transcripts and full details of how the information was obtained, to the FA, immediately. This information should not be provided selectively but unedited and unconditionally in order that a fully comprehensive investigation can be expedited.”
