Benfica midfielder Gedson Fernandes could come back to the club in January.
His loan at Tottenham has not gone the way he hoped, as he struggles to get into the first team.
Gedson's loan runs until the end of the season, and Spurs can buy him permanently.
But it seems unlikely, given his lack of playing time.
According to Jose Mourinho, the Spurs manager, Gedson can go back if he wishes.
He SportTV: "For me it is never a problem, but a solution.
"Having him in the squad, even if he is not called up and not playing, is an extremely comfortable situation.
"I will never be the one to push him or say that I don't want him here.
"But I understand the situation of the kid and Benfica.
"If the club wants to end the relationship here, we will be here to collaborate, because we want the good of the player.
"Benfica has the power to decide and will be accepted by us."
