Premier League duo Manchester United and Liverpool have been told to forget signing Brazilian international Lucas Rodrigues by his club Sao Paulo.
Both clubs have recently been credited with an interest in the player, who is also a reported transfer target for Serie A club Inter Milan.
A source from Sao Paulo told talkSPORT that they have no intention of selling the 19-year-old and only an "irresistible" offer would be considered.
"Our idea is not to sell and definitely not in January," said the source. "We would only be willing to let him go if an irresistible offer comes in."
Lucas has made ten appearances for the Brazilian national team.
