Benfica have reportedly put a €30million price tag on the highly-rated midfielder.
Benfica president Luis Filipe Vieira said: “The sale of players is the priority for Benfica but only if it is helping the club.
“Our aim is to break even and make around 50 million euros in the summer through sales.”
Benfica coach Jorge Jesus has reportedly been told that Gaitan is set to leave the club in the summer.
