Corriere dello Sport says Mutu's stunning early season form for club and country has sparked the interest of United, along with Barcelona, Lyon and Dynamo Moscow.

United have registered their interest in the former Chelsea forward, however Barca president Joan Laporta has stolen a march on rivals by making a £12 million offer in recent days.

Fiorentina are under no pressure to sell, having cashed in on Luca Toni, now of Bayern Munich, during the summer market.
