FC Barcelona are already looking at a possible replacement for Jasper Cillessen, and it could be a former academy player, according to Diario MARCA.
André Onana, who is Ajax's starting keeper now, could be the one set to replace Cillessen as the Copa del Rey keeper.
Cillessen himself came from Ajax to Barça and has enjoyed a triumphant time, winning the Copa del Rey twice as a starter. He's hoping to complete his third cup victory this season.
His performances for Barça and as the Dutch national team's starting keeper have made a lot of clubs interested in offering him an undisputed starting spot.
