The victory on Tuesday night saw Tierney net the decisive goal that secured Scotland’s spot in the World Cup next summer.
The tournament is set to take place in the USA, Mexico, and Canada.
However, Tierney’s goal meant that the Denmark squad finished in a play-off spot, with Brian Riemer’s side dropping five points in their final two games.
Despite this, Schmeichel sent a text to both Tierney and Anthony Ralston.
Tierney said [Sky Sports]: “No, he’s back tomorrow,” when asked if he had bumped into the keeper on his first day back in training.
“He actually sent me a lovely text after the game.

“Within an hour or so, he texted me and Ralston, so it just shows you the professional that he is as well.
“I said it after the game as well.
“Somebody’s got to lose, and in the last few years or however many years, it’s usually been Scotland in a game like that.
“So for us to have the fortune on our side and the moments on our side that night, it was really special, but obviously, it’s a shame for Kasper and his team as well.
“We’ve [Celtic] got plenty of big games and a cup final coming up.
“But of course, it’s a massive thing that people will be looking for at the end of the season.
“But before then, there’s another camp in March, and even before that, there’s probably 30 games before March.
“So, there’s a lot to focus on in the now before thinking too far ahead.”
