Talking points from Celtic's 3-0 win against Anderlecht
The Scottish champions ended a run of 16 games without a European group stage victory.
Keiran Tierney's engine, Scott Brown's hamstring and Olivier Ntcham's Jekyll and Hyde display all featured prominently in Brussels.
Celtic ended a run of 16 games without a win in European group stage football by cruising to a 3-0 victory in Belgium on Wednesday.
Here we look back on the main talking points as the Scottish champions went level with Bayern Munich in Group B.
Celtic and Scotland's prodigious young full-back Kieran Tierney has not been short of admirers over the last couple of seasons but his performance against Anderlecht offered further proof as to his potential.
The 20-year-old offered an attacking threat, setting up the first goal after producing a lung-bursting run down the left and a tempting cross for Leigh Griffiths.
He also defended in assured fashion, tackling with tenacity and sticking to his task throughout to keep Anderlecht at bay as they pressed forward.
Competing against some of the game's top wide men in Kylian Mbappe and Arjen Robben in Group B can only fast-track the defenders' development - good news for both club and country.
Dominating the ball has always been a hallmark of Brendan Rodgers' football philosophy and while it has been easy to implement on the domestic scene, the European stage has often proved a trickier platform.
On Wednesday, however, Celtic laid claim to the ball from the off and, despite some erratic early passing from Olivier Ntcham in particular, kept Anderlecht at arms length for the majority of the evening.
Celtic went into the break having enjoyed 72% of possession in Belgium.
While that lessened to 64% by the time the final whistle was blown as the hosts sought to salvage a point it played a major role in the end result.
Such a patient approach frustrated Anderlecht, with the Belgians desperate attempts to retain a foothold resulting in defensive errors on which Patrick Roberts and second Scott Sinclair would capitalise.
Olivier Ntcham drew the ire of the Celtic support during the opening half-hour as he handed over possession gleefully. The technical components are there but concentration seems to be an issue.
Despite possessing this erratic side one thing that can be said about the Frenchman is that he does not hide and he continued to seek the ball throughout the 90 minutes.
After a poor first half, Ntcham imposed himself on the game during the second period, working in tandem with Scott Brown to put out fires and keep the ball moving.
He possesses great physical characteristics and covers the ground excellently. Should he become more diligent in his forward passing, Brendan Rodgers will have unearthed a gem.
For all Celtic were good on Wednesday night, Anderlecht were bad.
Setting up in a 5-4-1 formation on their own patch was the sign of a team bereft of confidence and while they started well the wheels came off after Griffiths broke the deadlock.
Defensive errors crept in that Celtic happily took advantage of to extend their lead.
At the other end, Polish striker Łukasz Teodorczyk lumbered about haplessly, spending the majority of the game in an offside position to make it an easy night's work for centre-backs Jozo Simunovic and Dedryck Boyata.
A slight dampener was put on Celtic's evening when captain Scott Brown hobbled off with a hamstring injury.
Not only will an injury to the midfielder frustrate manager Brendan Rodgers, Scotland boss Gordon Strachan must have been left questioning his luck ahead of next weekend's crucial double header for the national side.
Scotland take on Slovakia at home next Thursday before the final game of the group in Slovenia on Sunday.
Brown now faces a race against time to be fit for either.
