Sao Paulo president Juvenal Juvenico says Chelsea target Lucas could be on the move this summer.
Chelsea's position could be strengthened after they were in negotiations with Sao Paulo only last summer when they competed the signing of young striker Lucas Piazon.
Any fears the teenager would baulk at a move to Europe early in his career could also be aided by walking into a Stamford Bridge dressing room that already boasts Brazil internationals Ramires and David Luiz.
"He is still deciding where he would like his future to be but those clubs that are interested are free to do so," Juvenico said.
"What must be decided at the end though should be decided with all relevant parties.
"He has had a great time here (at Sao Paulo) and will only leave for an important offer."
