QPR have launched an investigation after allegations about manager Jimmy Floyd Hasselbaink were made in Thursday's Daily Telegraph.
The Telegraph has published video footage of Hasselbaink and Barnsley assistant boss Tommy Wright as part of its latest report into alleged corruption in football.
Wright has been suspended while Barnsley investigate the claims, and QPR have also promised "a thorough internal investigation". Both men deny any wrongdoing.
Hasselbaink is alleged to have negotiated a £55,000 fee to fly to the Far East and speak to investors in a fictitious firm, which the newspaper says made clear it was interested in getting involved in player transfers.
QPR issued a statement in response promising "a thorough internal investigation" and said: "We have every confidence in our manager and the robust systems and processes the club has in place."

Hasselbaink has denied any wrongdoing and said he saw nothing "unusual in being offered to be paid to make a speech".
His statement added: "I did not make any promises in return. I did not and would not recommend the purchase of a player for my personal gain."
The newspaper, meanwhile, claims to have video footage of Wright accepting a payment it says was offered after the assistant manager agreed to help a fake agents' firm recruit players for Barnsley.
The club released a statement on Wednesday night which said: "Barnsley FC is aware of allegations made by the Telegraph against Tommy Wright. The club has today suspended Tommy pending an internal investigation into these allegations."
A spokesman for Wright told the Telegraph he denies any "acts contrary to criminal law or those of the FA and FIFA".
Leeds United owner Massimo Cellino has also been filmed by undercover reporters discussing FA rules on third-party ownership of players.
But the newspaper quotes him saying: "I cannot allow myself to make a mistake in England. I don't want to be the one that breach [sic] the rules."
A statement released in response by Leeds United read: "The Club has reviewed the supposed "evidence" that the Daily Telegraph have published. At no time in this video clip has Mr Cellino suggested getting around the FA's rules on third-party ownership of players."
The Telegraph has been conducting an undercover 10-month investigation and on Wednesday published claims from three agents that eight current or former Premier League managers took money for player transfers.
The League Managers' Association said it was "extremely concerned" by the allegations, while The __football Association, Premier League and EFL released a joint statement promising to investigate with "the full force of the rules" any "substantive allegations".
