Iker Casillas' recent performances have once again opened up the Real Madrid goalkeeping debate. According to 'A Bola', Madrid have their eye on Benfica's 21-year-old Slovenian keeper Jan Oblak, should Casillas leave the club.

A Bola's front page has re-opened a debate that was prevalent throughout last season. With Atlético de Madrid also interested in the Slovenian, according to A Bola, Jan Oblak's youth and potential would make him a great long-term signing.

After coming through the ranks at Olimpija Ljubljana, he then had stints at SC Beira, Uniao Leira and Rio Ave, before joining Benfica. He started last season on the bench, but earned his place in the starting XI over the course of the campaign .
