Luton manager Mike Newell claims to have evidence the director of a rival club offered him a bribe.
Newell has alleged that underhand payments are regularly being offered to managers by agents or club officials as 'sweeteners' to hasten transfer moves.
He will meet Football Association officials early next week to further discuss his allegations and the issues they raise - a summit that leaves him undaunted.
Newell has given fresh detail to his allegations, telling the Daily Express: 'I have the evidence and I will give it to the FA.
'I will present evidence of how a club official, a director, offered me a sweetener - a bribe - to sell him one of our players when we (Luton) were in administration.
'Perhaps I should have been shocked, but you know this kind of thing goes on.
'The director didn't say how much it would be because I wouldn't let it get to that stage. I was determined not to sell.'
Newell has agents in his sights too, and added: 'Agents have offered me cuts of transfer deals. I haven't got a long list to present to the FA, but there are instances I do know about.
'I know I have opened up a can of worms but it should have been opened a long time ago. I didn't want to know about the sort of money being offered, so I wouldn't go into sums - I wanted to be able to sleep at night.
'But what I know about my level in the Football League is one thing - knowing the huge sums involved on players in the Premier League, these sweeteners must be massive.'
