Bristol City, their Nigerian forward Enoch Showunmi and the agent Charles Collymore have been charged with misconduct relating to Showunmi's move to Ashton Gate in 2006.
City have been charged with breaching a Football Association rule after allegedly dealing with an unlicensed agent for the registration of Showunmi between May and July 2006.
The club are also alleged to have paid Collymore £30,000 for services provided by him under a representation contract with the club knowing the payment was partly or wholly for services provided by an unlicensed agent.
City said in a statement: "The club is very disappointed by their decision to bring these charges and denies the allegations strenuously. It will respond in full to the FA by 18 April."
The FA said Showunmi "had been charged with engaging the services of an individual, who was not a licensed agent or entitled to act in such a capacity, to represent him in contract negotiations with Luton Town in or around February 2004 and between November 2005 and January 2006. He is also charged with using the same person for contract negotiations with Bristol City in or around May to July 2006."Reuse content
