Multiple sources have confirmed that Roma have officially submitted a bid for Mason Greenwood. The offer for the Marseille forward had been speculated for a number of weeks, but represents the first concrete bid for the player. While negotiations continue, they are said to be progressing. Roma have laid out their intentions, but valuation and timing remain under debate. Paris FC, Juventus and Man Utd are keeping tabs in case talks collapse or progress slows further. At 1.53 goals scored per game this season, Roma already pose a big threat. Mason Greenwood would be expected to maintain that level and give them another reliable option in attack. There are currently no rumoured links for either Marseille or Roma. More on this story as it develops. Need more Roma transfer rumours?
