Reports have claimed that Inter Milan have made a bid of around €25million for the 19-year-old.
But Sao Paulo insists that a bid of €25million would be far too low for the youngster.
Sao Paulo vice-president Joao Paulo de Jesus Lopes told Lancenet: “There are no bids, but €25million is ridiculous, they can’t pay that for a player like Lucas [Moura].
“We refused better offers than that.”
Real Madrid, Chelsea and Manchester United are also reportedly interested in signing the midfielder.
