Munich's streets have had a slight snow powder in recent days. With penetrating blue skies, there are certain areas of the city of which the Bavarian Alps have been visible.
Located further south, near the border with Austria, the mountains are covered with a white blanket and offer an impressive backdrop for this strength of European football.
While the landscape can be cold and picturesque, nobody expects this place to become a wintering country for Celtic when they go out to the field in the Allianz Arena on Tuesday night.
Those mountains in the distance serve as a visual representation of the task that Brendan Rodgers faces and his players against Bayern Munich.
Before the first game last week in Glasgow, Rodgers described Bayern as the European 'royalty' royalty. Looking at their record, few would play such a large status.
Winning three successive European glasses between 1974 and 1976, Bayern's original golden era was based on the talents of Franz Beckenbauer and Gerd Muller, players for whom the success extended to the national team of West Germany and a World Cup triumph in the '74.
Bayern fans enter Allianz Arena, where Celts face a gigantic task on Tuesday night
Brendan Rodgers knows that his team will have to be at his best against Bayern
The last time Bayern did not reach the last 16 was 2003, when Jamal Musiala was born (above)
The modern Bayern has accumulated three other titles of the Champions League in the last 25 years (2001, 2013 and 2020). Only Real Madrid and AC Milan have won more.
To distill things a little more, the Bayern local record in the Champions League in the last 15 years distinguishes them as probably * the * most discouraging opponent Celtic could have chosen when trying to cancel a deficit of 2-1 from the match outward.
German giants have not lost at home in this tournament in almost four years, a race that goes back to a defeat against Paris Saint-Germain in the quarterfinals in 2021. Even that was an atypical case.
In the group Games of the Champions League, they have won 32 of their last 33 games in the Allianz Arena, a space creation on the outskirts of the north of the city that houses 75,000 fans.
His record in knockouts is no less formidable. In the last 19 years, the only teams that have won a game knocked out in Munich are Real Madrid, Liverpool, Inter Milan, Psg and Arsenal.
If Celtic add your name to that list, it would be located not only as one of the biggest clashes of all time in the Champions League, but as one of the best results in the history of the club.
The last time Bayern Munich did not reach the last 16 was in the 2002-03 season. For the context, that was the year Jamal Musiala was born.
Since Celtic has never won a competitive game in Germany, it is not difficult to see why many feel that Rodgers and their players embark on the football equivalent of the impossible mission.
Bayern coach Vincent Kompany is silent that his team will progress on Tuesday
Munich has been a cemetery for Scottish sides in the past, including the national team
Rodgers tried to wake up his team at greater heights in the 2-1 defeat in the first leg in Celtic Park
Munich has been a cemetery for Scottish teams. Last summer, in the opening match of the euros, Scotland was hit 5-1 by an unbridled Germany in this same place.
Musiala played a leading role that night, destroying Scotland in a brilliant exhibition of attacking football.
He is confident that he can produce more than the same on Tuesday, the young Bayern Munich attacker said: 'I had a lot of fun that night. It was one of my favorite games in my career.
'We wanted to start the tournament well, we knew it wouldn't be easy. But finally we found our rhythm and it was very fun. Hopefully it is similar in this game.
In 2017, during Rodgers' first period as Celtic manager, his team was defeated 3-0 in a group game of the Champions League here. To tell the truth, there were three of five or six.
With one of the most scored faces in Europe, there is a danger that they can become lambs into a Bavarian slaughter.
As was the case on his previous trip to Germany last October, when they were mistreated by Borussia Dortmund.
That Celtic recovered from humiliation to claim a place in the play-off round is an achievement in itself, and one for which Rodgers and his players deserve credit.

The victories about RB Leipzig and the young people, as well as the raffles against Atalanta, Club Brugge and Dinamo Zagreb, sat the platform for the club to reach their first draw of the Champions League in more than a decade.
In that sense, the campaign has been a success. Now Celtic has reached the play-off round, just to meet a true European superpower. They have no real right to progress.
That said, the success of this campaign will also depend on showing the ability to remain in the fight on Tuesday. Celtic does not dare to repeat Dortmund's mistakes.
If they do, this could become a score of Crickt in the blink of an eye, regardless of whether Harry Kane plays or not.
Kane is breastfeeding a facial injury and Bayern will make a late call on whether or not to risk the captain of England.
“Nothing changes in terms that we need to win the game and we want to win the game,” Rodgers said.
'If Harry does not play, then, of course, it is a great fault for them. But I am quite sure that there is another world class player who can enter and play. I would expect Harry to play.
After Dortmund's debacle, Celtic showed a much greater composure and maturity in the Champions League, especially in claiming an invaluable point to Atalanta.
Rodgers needs to create a great plan if your team has any opportunity in Munich

Captain McGregor says that Celtic will have to produce his best performance to progress
The growth and evolution of this team will be evident in how they are going home against a team with the fire power of the leaders of the Bundesliga of Vincent Kompany.
No Scottish team has won in Munich. The possibilities of Celtic change that are remote, to say at least.
However, if they can remain in the fight and bother life for Bayern, Rodgers and their players would sign this European campaign with a solid loan in the bank.
The inclusion of Daizen Maeda playing as a central striker must surely be a key part of the game plan.
When he moved from the left to a central role in Glasgow last week, there was a notable improvement in Celtic's ability to hunt Bayern higher in the field.
With its implacable energy to press, deploying Maeda in the middle is the only decision facing Rodgers in terms of the team's team.
Given the horror program that took place on his last trip to Germany, and the criticisms that followed, this feels like a season of decent progress in the Champions League.
Celtic has recovered and shown maturity. If this will be your last hurra in the competition this season, it is important how they are signed.
The scale of the challenge is clear. With those mountains that are coming in the distance, Celtic is trying to climb the Everest of football.
