I feel like this is an obvious one, but most people seem to think Barcelona would win. Heres why I think itd be Bayern:

• Bayern demolished Barcelona in 2013 7-0. That Barca team had the same core players, and they had 100 points in la liga. Barca fans will try to make excuses, but the reality is that this was the same group of guys with similar tactics.
• The same guys won euro 2012 without pep and Messi holding their hands. Xavi, Iniesta and Busquets all played in that match, and they couldnt control the game like they usually do. Its clear that this has nothing to do with their coach having cancer, and rather its more related to the opposition countering their style of play.
• Iniesta was 29, Busquets 24 and Xavi was part of 2012 euro team of the tournament so he was still good.
• Bayern only lost 2 games that whole season, it was a very good team.
• They used a complex pressing tactic that would have worked on Peps team. Pep’s teams had some trouble with Klopp which tells you that he isnt great against that style, especially not in his early years. I think Dortmund would have also given them trouble.
