Brendan Rodgers' side took the lead with seven minutes remaining of the first half, courtesy of Leigh Griffiths, but the strike was notable for the build-up before the final finish, tremendous teamwork on display from Celtic on the way to taking the lead.
Celtic posed little threat for much of the half until a moment of inspiration from 20-year-old Tierney stirred the match into a life.
CELTIC eased to a comfortable 3-0 win against Belgian side Anderlecht at the Constant Vanden Stock Stadium. "To come away and get a 3-0 victory, play that well after such a big game at the weekend [against Rangers] really shows how the players have grown and are believing at this level".
"We won, not with relative ease but with a real good professionalism, with players who look like they belong at the level", said Rodgers.
"The message I gave to the players when we came in here 15 months ago was: 'Lots of people will tell you what you can't do, '" Celtic's manager explained.
"In spells with the ball we were very, very good".
It was another feather in Rodgers" cap as he attempts to add renewed European credibility to the Scottish champions after leading them to an unprecedented "Invincible' domestic treble last season.
"When Celtic are in the Champions League, everybody expects them to just get beat by whoever they're up against", said Wright.
"You saw the concentration of the players - how many times Anderlecht were caught offside, our defensive line was very good".
Nigerian forward, Henry Onyekuru, and his teammates in Anderlecht will earn £35,000 each if they defeat Scottish Champions, Celtic in Wednesday's UEFA Champions League Group B game in Brussels.
"It takes experience and time and it takes belief".
The defender was released in behind by Olivier Ntcham's incisive pass and fed a flawless low cross from the left to the far post, where Griffiths was waiting to tap in the opener.
