Bayern Munich Face Champions League Acid Test vs. Roma After Bremen Win

This weekend's Bundesliga action was simply business as usual for Bayern Munich, as they thrashed bottom-of-the-league side Werder Bremen, 6-0, to cement their position at the top of the table. 

It would be fair to suggest that the Bavarian club have had an easy time of it so far this season. While Borussia Dortmund continue to struggle with their injury crisis, Bayern have now gone 10 games without defeat in all competitions. 

Pep Guardiola's team have also gone eight games without conceding a goal—a total of 748 minutes. Bayern are simply cruising at the minute. 

There are plenty of reasons for this: Guardiola's meticulous planning, Bayern hitting the ground running and having an incredibly strong squad being just three. Yet, the main reason is simply because they haven't faced any decent opponents so far. 

We are likely to see that change when the German champions make the trip down to Rome this week, when they take on Italian side AS Roma in the Champions League on Tuesday night. There, they will face one of Serie A's most in-form sides and perhaps their first real test of the season. 

Manchester City and CSKA Moscow fans will undoubtedly disagree with such a sentiment. Yet, there's no denying that the English champions and Russian team offered little when they faced Guardiola's team.

The City side that faced Bayern back in September was far from the the team that disposed of Tottenham Hotspur with relative ease on Saturday. Sergio Aguero was far from fully fit, David Silva was off his game and Vincent Kompany hadn't looked himself in months. Bayern brushed past their English counterparts on the night and continued their search for a worthy match. 

Then came their trip to Moscow, which actually saw Bayern scrape a 1-0 win. Yet, rather than CSKA offering much to stop Guardiola's team, it was instead the Bavarians' own ineptitude in front of goal that made brows sweat in the cold, Russian winter. 

Similarly, the Bundesliga has offered very little for the Bavarian club to test their mettle against. To date, we've had nothing but a win against Wolfsburg and a draw against Schalke in Gelsenkirchen to suggest that Bayern won't win this title.

Gladbach and Dortmund still await—the Foals are set to face Guardiola's side next weekend—but again we're still waiting for this team to draw blood. 

This is where Roma come in. As we saw in their own clash with City in Manchester, Rudi Garcia's team tend to leave no stone unturned against opponents big and small and should make things uncomfortable for Bayern in the Stadio Olimpico on Tuesday.

Where Xabi Alonso would typically casually dictate the tempo of Bayern's midfield, the Spaniard will instead be looking over his shoulder in constant worry of Radja Nainggolan's tackles and interceptions. Where Robert Lewandowski would tend to kill games off with his well-executed goals, he will now be called into question against the skill of Davide Astori. 

The Italian side also have plenty to hurt Bayern with. Whether it's Mattia Destro's goals, Francesco Totti's assists or even Gervinho's marauding runs, Roma have the quality to beat Bayern and could well be the first side to do so this season. 

Unlike any foe that has come before Guardiola's behemoths so far this season, Roma have the form and quality to cause a major upset in the Champions League on Tuesday. Garcia's side will have no fear going into this match and seeing how Bayern react should prove most entertaining. 

It's the toughest competition in world football, and it looks to have finally found a test for Bayern.
