A football manager has named an agent who he says attempted to bribe him.
Luton Town boss Mike Newell
Luton Town's Mike Newell says freelance football agent Charles Collymore offered him a cut of a player's fee that he tried to negotiate.
Newell told Panorama that he rejected the offer and reported the agent to the Football Association.
In undercover filming, Collymore told the BBC there were up to eight Premiership managers who would accept illegal payments known as bungs.
Collymore made the allegation to a Uefa-licensed coach Knut Auf dem Berge, who worked undercover for Panorama for nine months on an investigation into corruption in football which will be shown on Tuesday night.
But Collymore denies offering or accepting any bungs and says he gave Knut Auf dem Berge false information because he was suspicious of his agenda.
Newell met with the Football Association in January to discuss his allegations that transfer bungs are rife in football.
He claimed that "a lot of people involved with the agents and doing the deals are taking back-handers".
Shortly afterwards, the then England coach Sven-Goran Eriksson told the News of the World newspaper that three unnamed English Premiership clubs were riddled with corruption.
The alleged corruption related to illegal payments in transfer deals.
In March, Lord Stevens, the former Metropolitan Police Commissioner, was appointed as head of a probe into alleged transfer bungs in the Premier League.
He is looking at irregular payments in transfer deals made since 1 January 2004 and he is expected to publish his findings in the next few weeks.
