Tierney focuses on Europa league as Celtic meet Rosenborg
Kieran Tierney is not experiencing any Champions League withdrawal symptoms as Celtic prepare to take on Rosenborg in their opening Europa League Group B game on Thursday night.
The Hoops qualified for the group stages of European club football's elite club tournament in the first two seasons of boss Brendan Rodgers' tenure.
However, defeat to AEK Athens in the third qualifying round this season, after Celtic had knocked out Rosenborg, meant the Scottish champions dropped down to Europa league where they were drawn in a section which includes the Norwegian champions, Salzburg of Austria and German side RB Leipzig.
The Scotland defender said: "The Europa League is another great tournament.
"It's a huge honour to represent Celtic at it as well. I'm grateful for the chances I've got here so if I can play tonight then that's brilliant.
"Another tough test for us. Every game's hard home and away and this will be no different.
"The aim is always progression. We would like to go through of course. The aim is to win all our home games and pick up what we can away.
"We know what we're in for. We've played them and did our video analysis as well, I'm sure they have, so it'll be a tough game.'
