The 19-year-old is one of the hottest prospects in Brazil and the player's agent Wagner Ribiero says that United and Chelsea have already been in touch about a possible move.
Despite his tender age, Lucas has already made 87 appearances for Sao Paulo scoring 23 goals and watching scouts have been impressed with what they have seen.
The player has all the attributes to make it big in England and Ribiero claims United, Chelsea and Inter Milan are interested should Sao Paulo decide to sell.
"Lucas already has what it takes for Europe, and the clubs know that. He is strong, quick and can shoot well. I have already been contacted by Inter, Chelsea and Manchester United," he revealed.
Sao Paulo insist he is not for sale at this time and only a bid of £66million, which would activate a release clause in his contract, would force through a move.
