Rangers' two-year Barclays Premier League stint was brought to an end with a draw at Reading last weekend and manager Harry Redknapp has already claimed he wants to clear out a lot of the current squad and rebuild over the summer.
Mbia moved to QPR from Marseille last summer and it appeared he had contacted Joey Barton, who moved to the Ligue 1 club on loan as part of the deal, on Twitter to ask if he would like to swap clubs. But both the player and representatives of QPR have claimed Mbia's official Twitter account had been hacked and he had no idea of the incriminating messages.
A public message was sent from Mbia's account to Barton, seemingly suggesting he was looking to leave Loftus Road during the summer. It read: "So... Seriously @Joey7Barton do you want rechange your seat with me ? #qpr #om"
Ian Taylor, the club's head of media and communications, said he had spoken to Mbia and released a statement via the social networking site.
It read: "The club is aware of tweets from the official twitter account of #QPR midfielder Stephane Mbia. Stephane Mbia has informed the club he is not responsible for these tweets. The club will continue to investigate and deal with the issue internally."
Mbia also tried to clear up the matter: "I do not know how this happened," he told the Guardian. "Someone must have got hold of my login and password because I did not write these things.
"This was not me. I did not write the tweets, and I have made people at the club aware of that. I saw the messages this morning and spoke with the club about them, but now I see there are more appearing in my name."
Barton, who was sent off on his last appearance for QPR and was handed a subsequent 12-game ban, has repeatedly told of how he is enjoying his time in France with Marseille and was quick to respond to Mbia's request.
"How do I answer this politically? Er...Nope #allezLOM," he replied. "If you go down with a team, you should stay and help them up mate. They need you all to stick together and help them back."
