George's agent, Emeka Obasi, has offered the player to Roma, and Massara is interested in bringing him to the Italian club.
However, Chelsea is asking for a significant amount of money, €20m, which is a price that Massara is having trouble agreeing to.
George was previously offered to Manchester United in a potential swap deal for Alejandro Garnacho, but it appears that Chelsea is now looking to sell him instead.
