Despite having a year left on his contract, 28-year-old Aboubakar is open to a move after struggling for game time in Sergio Conceicao’s side.
Once one of Porto’s most prolific players, Aboubakar has suffered badly from injuries and has lost prominence at the club.
This season, the forward has managed just five appearances in Liga NOS, four of them from the bench.
Turkish club Besiktas, where Aboubakar scored 19 goals during a loan spell in 2016-17, have expressed an interest.
At this moment, it is uncertain where Aboubakar’s future lies. He likes Porto and feels cherished by the fans, but wants to play regularly next season.
