Scotland head coach Steve Clarke faces a crucial decision on his defensive pairing for Saturday's friendly against Japan. During World Cup qualifying, Clarke constantly changed his center-back combinations, using Grant Hanley and John Souttar most frequently but also deploying Scott McKenna, Jack Hendry, and Dom Hyam at various points.

The current situation presents challenges as Hanley recently missed six Hibernian games through injury, while Souttar has been limited to substitute appearances at Rangers. Meanwhile, McKenna excels in Croatia with Dinamo Zagreb, and Hendry faces elite competition in the Saudi Pro League. Former Scotland boss Craig Levein favors a Souttar-McKenna duo for their balance and experience.

Despite the successful World Cup qualification, Scotland conceded six goals in their final three qualifiers. Clarke and his coaching staff will analyze performance data closely, noting Scotland was dominated for large periods against Denmark despite victory. The defensive setup needs significant improvement before Scotland faces Haiti in Boston next month.
