Benfica coach Jorge Jesus has confirmed that Joan Capdevila is the club's second pick for the left side of the defence.
The 33-year-old defender joined the Portuguese giants on a free transfer in the summer with hopes of filling the void created by Fabio Coentrao's sale to Real Madrid.
However, the Spaniard has found himself behind Emerson in Benfica's pecking order and was omitted from the club's 25-man squad for the Champions League.
Capdevila's agent has made no secret that his client has grown unsettled at the club, with Juventus and Napoli reportedly monitoring the player's situation.
Jesus says that Capdevila has a part to play in the season, but conceded the defender will have to work hard to get to play.
"I count on Capdevila," he said at a press conference. "He is part of the squad but he arrived after Emerson.
"He plays in a position in which either you are the first pick or you are not included in the squad for matches.
"Emerson has been our first option, so I do not need to take another full-back to the bench to risk running out of options in other areas."
