It is difficult but not impossible for Barcelona to beat Bayern Munich. Since this match is unimportant for Bayern Munich. So maybe they will put their key players on the bench. If that happens then Barcelona has a chance to win. However, Barcelona are now weaker than Bayern's second squad. If Xavi can improve Barcelona's performance by devising new plans and strategies, then maybe Barcelona has a chance to win.
This is true, but my analysis is made with a view to the future of the competition.
The market opens in January, it is true that financially Barcelona is not doing well, but being Barcelona it can be strengthened in the next transfer market. There is a chance that in a few months Barcelona will be much better.
If they stay in the competition, there could be a chance that Bayern will meet Barcelona again. Do they want this confrontation?
Maybe it's better that they've warded off a potential adversary now, rather than having to face him in the future.
That's why I think Bayern won't make this game easier.
