The 19-year-old Sao Paulo star is now learning English ahead of a possible move to England.
Lucas’ agent Wagner Ribeiro revealed: “Chelsea, Inter Milan and Liverpool have demanded details from me and Sao Paulo knows the situation.
“At the moment they are not interested. Perhaps in the summer they may negotiate but only an enormous offer could change things as I want continuity for the player for a couple of years.”
Lucas said: “Three days a week I study for one hour with a teacher.
“I’m prepared to move to Europe and it is always good to get on top of the language.
“I haven’t decided what I’m doing. For now I’m concentrating on Sao Paulo.”
