Olympique Lyon attacker Sidney Govou wants a move to Roma.
"He has been playing for them for seven years and there's a sort of agreement with the President that he can leave if he wants to."
Roma and Lyon may be discussing the possibility of Amantino Mancini moving the other way in January and Govou may be included in the deal.
"I wouldn't rule out Govou being linked with a deal for Mancini," Guerra admitted. "We have excellent relations with Lyon and there are lots of options."
