If the reported squad list holds, Tierney looks the more central figure. He has long been one of Scotland’s most important outlets from the back, whether used as a traditional full-back or in a more flexible defensive role.
That matters in tournament football. Managers lean toward players they trust, especially early in the group stage, when rhythm and control can be more important than experimentation.
For Ralston, the picture appears different but still significant. Reports suggest he may begin the tournament as a squad option rather than a guaranteed starter, yet that should not diminish the call-up.
A reliable deputy can become crucial quickly if form dips or fitness issues emerge. In short competitions, the bench is rarely just the bench.
Even before the season fully closes, attention is already shifting. Celtic still have club business to handle, but international recognition for Ralston and Tierney would reflect the club’s continued ability to produce or sharpen players for elite occasions.
Scotland’s reported opener is against Haiti at Gillette Stadium in Foxborough, a match that could immediately shape the mood of the campaign. If the squad news is confirmed, the next storyline will be simple: how heavily Clarke leans on his Celtic contingent when the tournament begins.
