Celtic's new signing, Sebastian Tounekti, has only three international caps to his name.
This season is crucial for Tounekti, with two major tournaments on the horizon: the Africa Cup of Nations and the 2026 World Cup.
Despite being called up, Tounekti was left out of Tunisia's main squad for the World Cup qualifier against São Tomé and Príncipe, which ended in a 6-0 win.
The reason for his absence is an injury, which is both good and bad news from a Celtic perspective.
Celtic have significant games coming up after the October international break, and Tounekti is expected to play a huge role.
Tounekti's injury is the simple answer to his current situation.
