Recent reports have suggested that Chelsea had made a play for the Frenchman but nothing has been heard by his camp.
"I have seen the rumours linking Philippe with Chelsea, but I have heard nothing," Joanneaux told skysports.com.
However, Joanneaux said if the Blues did come forward with an offer, his client would definitely consider it.
"He has two years left on his contract and Philippe is happy with his situation at Roma.
"But if Roma decide to sell him we will consider all options available."
