Alvaro Morata can leave Atletico Madrid for a cut-price fee this summer.
Relevo says Atletico are happy with the striker, but know he can leave the club should a club activate his buyout clause.
The clause is only 15 million euros.
After Morata went over to the fans to say goodbye during last weekend's final home game and his partner posted a photo of the farewell on social media, a move is looking increasingly likely.
The striker has previously been contacted by clubs in Major League Soccer and Saudi Arabia.
