Scotland scored two goals in stoppage time in the final round of the World Cup preliminaries, defeated Denmark 4-2, and advanced to the World Cup in a thrilling manner. Tierney's goal in the 93rd minute was very crucial.
In an interview after the game, Tierney joked that he might have to avoid teammate Schmeichel after returning to Celtic Club, because the latter's Danish team will have to participate in the play-offs.
Tierney said: "That's the sad thing about football, someone always loses. If it were the other way around, it would be very sad for us, but we've been through enough."
"We deserved to get a chance to advance. The atmosphere was so crazy. I ran to the dugout and everyone was standing up, including the coaching staff, substitutes and staff.
"I think this shows one of our greatest strengths, which is that we are always united in good times and bad. We support each other and have high hopes for each other.
"The coach said before today's game that everyone is important, whether they are playing or not, we need to go all out, and in the end this team did it. "
