Barcelona want to keep hold of Joao Felix next season.
Felix is currently on-loan at Barca from Atletico Madrid for the season, without a permanent option.
But Sport says Barca have already seen enough and want to extend Felix's stay.
Barca would prefer a new loan arrangement, though know Atletico would prefer an outright sale as they prepare for negotiations to kickoff.
Barca upgraded Felix's salary from 400,000 to 4m last week after Financial Fair Play restrictions were eased as they sought to reward the player for his form.
A Barca source said: "We have the whole season to prepare a proposal that allows us to keep Joao Flix. We are very happy with his performance and he is a player who is well-liked in all areas of the club."
