After leaving Napoli for the Portuguese giants last year, the 24-year-old has contributed 15 goals from 23 appearances in all competitions.
The Brazilian's form has naturally led to interest from elsewhere, including from Liverpool who are keen to strengthen in the final third.
According to AS, Benfica may be willing to consider offers in the region of €60m (£50.35m) at the end of the season.
That would represent a significant profit, with Benfica spending just over £14m to sign the attacker in June.
While the player has a release clause of €100m (£83.91m), there is an acknowledgement that they will not be able to recoup that sum.
