The English Football League said Wednesday it was satisfied that Championship side Wolverhampton Wanderers' relationship with super-agent Jorge Mendes has not breached regulations regarding intermediaries.
Last month a number of clubs urged the league to investigate the influence at Molineux of the high-profile Portuguese agent, whose clients include Jose Mourinho and Cristiano Ronaldo.
Mendes, who has no official title at the club, has a number of clients at Wolves including head coach Nuno Espirito Santo, midfielders Ruben Neves and Diogo Jota, who is on loan from Atletico Madrid, and winger Ivan Cavaleiro.
Those players have been pivotal in Chinese-owned Wolves winning the title this season and clinching promotion back to the Premier League, and the EFL's investigation has concluded that the club has no case to answer.
"Discussions between the EFL and management of Wolverhampton Wanderers have now concluded in regard to the matter of the relationship between the club, majority shareholder Fosun and intermediary Jorge Mendes," said a statement issued by the EFL.
"Following the commitment made in March, as a result of some concerns raised by a number of Championship clubs, the EFL has met with Wolverhampton Wanderers to ensure compliance with the requirements of its regulations.
"At that meeting, a request for information was made by the EFL and, following a comprehensive review of the detail subsequently provided by the club, it has been determined that Mr Mendes holds no role at the club and, as such, should not be categorised as a 'relevant person' as defined by league regulations. On this basis there is no requirement for him to submit to the owners' and directors' test."
