Celtic right-back Anthony Ralston and Hoops-bound Kieran Tierney played a vital part in Scotland's hard-fought Nations League play-off win over Greece on Thursday night.
Steve Clarke's men took a 1-0 lead in the first half through Scott McTominay's spot kick and did well to withstand an onslaught of pressure from the hosts in the second 45.

It was a solid performance at right-back from Ralston, who won his individual battles and put in the most duels (8) of any player on the pitch. He was eventually substituted in the 89th minute for Ryan Porteous after a defensively disciplined display.
Arsenal left-back Tierney, who will rejoin Celtic in the summer, made his first appearance in a Scotland jersey since suffering a hamstring injury at Euro 2024.
