The agent of Bordeaux fullback Julien Faubert has warned Roma they must up their offer if they want to sign the defender.
Vincenzo Morabito said: "If Roma wants Faubert, they will have to increase their offer of £2.5 million up to £4-5 million at least, otherwise the player, that above all has other offers from England, will go elsewhere.
"The club is insisting on a hardline - they want to keep the player, while his will is to leave."
