31-year-old Isla has been with the Turkish giants since 2017 after joining from Cagliari. His contract expires in June and he will be leaving the club.
Like Isla, the right-back is out of contract in June. However, Molina is a much younger player at 22, so would be a long-term signing for Fenerbahce.
Despite great efforts by league leaders Boca, Molina has no intention of renewing his contract and is likely to leave the Argentine giants.
Fenerbahce have already made contact with Molina’s representatives, hoping to sign him as Isla’s replacement.
In the 2019-20 season, Molina has played 16 games in Argentina’s Primera División, scoring once and assisting three goals.
