The agent of Bruma admits the Chelsea target sees his future beyond Sporting Lisbon.
Manchester United and Porto are also believed to be looking at the player, but Balde has previously said the only bids have come from Chelsea and Galatasaray.
Chelsea's offer is reportedly around £1.7m but the Turkish club's bid is substantially larger, says the Daily Mail.
Catio Balde said: "From this moment on, considering that he is a highly-coveted player, it is possible that more offers will arrive, because I know that several clubs were waiting for the best moment to make a move.
"Right now, Bruma's mind is not on Sporting."
