The Iranian is advisor to Mark Hughes, who on Thursday was installed as the new Stoke manager, and he insists he was only involved in bringing Julio Cesar to the relegated club
The 41-year-old has revealed that Brazilian goalkeeper Julio Cesar was the only player his company represented during Mark Hughes tenure at the club.
The Welshman, who was sacked after losing the first 12 games of the season, signed 16 players during last summer's transfer window before current manager Harry Redknapp added a further six in January.
"I'm always interested to read or hear that I was responsible for so many of the players signed by QPR last season," Joorabchian told BBC Sport.
"In fact my company was only involved with the signing of one, Julio Cesar."
New signings included the likes of Bobby Zamora, Djibril Cisse, Samba Diakite, Esteban Granero and Park Ji-Sung for a reported combined fee of £25 million, but the club failed to avoid relegation to the Championship come the end of the 2012-13 season.
The Iranian is still advisor to Hughes, who on Thursday was installed as Stoke's new manager following their decision to part company with Tony Pulis.
