Brussels - Celtic took a big step towards securing at least a spot in the Europa League on Wednesday when they beat Anderlecht 3-0 away from home in the Champions League.
With Bayern Munich and Paris Saint-Germain (PSG) being the undisputed favorites to advance from Group B, goals by Leigh Griffiths and Scott Sinclair, along with an own-goal by Kara Mbodji, gave the Scottish champion an important victory.
A third-place finish would secure a place in UEFA's second tier competition.
The win underscored Celtic's great start in the Scottish league, where they lead the table and are fresh from a victory over Glasgow rivals, Rangers.
After PSG beat Bayern 3-0, the French champion lead Group B with 6 points from two games, while Celtic and Bayern are tied on three, with Anderlecht at the bottom with zero points.
In the 38th minute, Griffiths finished off a smooth team move by tapping the ball home unmarked, with the Anderlecht defense in disarray.
In the 50th minute, Mbodji turned a shot from Patrick Roberts past his own goalkeeper following more defensive bungling.
Sinclair capped a great Celtic performance with a third goal in injury time.
