Bolton chairman Phil Gartside has promised an investigation into claims of an alleged illegal approach to Nigerian midfielder Jay-Jay Okocha.
Reports have linked Okocha with a move to Al-Rayyan in Qatar.
Gartside insists Okocha is not about to leave and says an investigation will take place as to whether an illegal approach has been made.
"We will be investigating the possibility of an illegal approach," he confirmed to the club's website.
The possibility of losing Okocha will be of concern to Bolton manager Sam Allardyce, who is also facing a battle to keep Stelios Giannakopoulos from joining Manchester City.
Allardyce has already stated that he would like to sign five players to bolster his squad before the transfer window closes.
But Gartside insists that Okocha is not about to leave the Reebok Stadium.
"Jay-Jay is a vital asset to our football club and we have not received any offers for him whatsoever," he added.
"He is the captain and one of our most important players.
"He is under contract to this football club and there is no way we would want him to leave, especially with the season only just commencing."
