Roma striker Paulo Dybala is at the centre of a South American transfer tug-of-war.
Boca Juniors are keen to bring the Argentina international home this summer as his Roma contract winds down.
Boca are in contact with Dybala and have made an initial contract offer to the attacker.
However, UOL says Brazilian giants Flamengo are also in the mix and have made a proposal of their own.
Fla are offering Dybala a four-year contract on superior terms than what Boca have tabled.
Those close to the 32 year-old admit the veteran now faces a choice "between his heart and his wallet" given the two offers now in front of him.
