I have been watching almost every Bayern Match since the summer of 2013. Last season their team tried to match the tiki taka of the Barca of old, and they produced some stunning performances, like the 3-1 victory over man city and the 3-0 victory over dortmund. But Guardiola's 13/14 Bayern at best looked like a very authentic counterfeit of his 2010/2011 Barca, they employed the same tactics but Bayern was not as sharp, not as fluid, not as beautiful and they lacked Messi. Bayern capitulated in their 0-4 defeat to Real Madrid, a defeat which exemplified all the "problems" associated with tiki taka, such as passing and keeping possession with no penetration, sacrificing effectiveness for aethestics and slow build up play.
This season however he has constructed a different team, instead of trying to be barca 2.0 he has built a side which plays on Bayern's strengths and limits their weaknesses. They look more effective, more solid and more dangerous than last season.
That being said they have still been better than us since the 2012/13 season, and I think they are the best team in the world this season
