The Ghanaian will join Real Madrid Castilla for the 2027-28 campaign after the clubs finalised the transfer on Thursday. He is expected to remain with UD Logroñés until the end of the current season.
The agreement makes Issman the first signing secured by Real Madrid for their next campaign. The club have been monitoring his development since the summer and accelerated their efforts during recent weeks.
As reported by MARCA, the relationship between the two clubs helped facilitate negotiations. They had previously worked together on the transfer of Manex Rezola to Valdebebas during the previous winter window.
Issman was born on November 1, 2006, and began his development with SD Logroñés before moving to UD Logroñés at youth level. He progressed into the senior squad in July 2025 and has since established himself as an important member of the team.
His opportunities increased during the promotion play-offs, when coach Unai Mendía gave him minutes in all four matches. He subsequently made an immediate impression in Primera Federación, starting seven of the club's first nine league fixtures.
The midfielder has made 10 league appearances this season, eight from the beginning, and has provided one assist. His physical presence and ability to carry the ball through midfield have attracted attention from several clubs.
AS reports that the transfer fee is relatively modest, although additional payments could be included depending on performance-related objectives.
Issman is viewed as a player capable of providing balance in a double-pivot midfield, while also possessing the athleticism and forward movement to contribute further up the pitch.
Real Madrid will now allow him to complete the season in Logroño before making the next step in his development at Castilla.
