The Argentina international has been linked with the likes of Valencia this summer but has made it clear the club must decide if they no longer want him
The Argentina international enjoyed a superb campaign for the Portuguese treble-winners last season, earning the title of Portugal's player of the season as well as a place in the Goal 50.

Perez is also hoping international team-mate Sergio Romero moves to Estadio da Luz after his loan spell with Monaco came to an end.
The goalkeeper returned to parent club Sampdoria, but is believed to be close to completing a switch to the Portuguese capital to replace new Jan Oblak, who has joined Atletico Madrid.
"During the World Cup I told him about the club," Perez added. "He is a great person and a better professional.
"Benfica need people with experience in the squad."
