I don't think I can say that it took long for Barcelona to reach the level of Bayern Munich (what does level really mean in the game of football?). The reason is, that the match has not happened and can not measure how far the difference between the two is and how far behind Barcelona from Bayern Munich is. In football, nobody always wins right? Well, this also applies to Bayern Munich when it comes to dealing with Barcelona.
Barcelona have unbeaten until five games in domestic league and one game on UEFA Champion League, most drastically different with Barcelona performance in this season than Bayern Munich. I think all Barcelona fans not worry with bad memorize when last match against with Bayern Munich defeated 8-2, probably with Bayern Munich not on the top performance after got draw last match and have been three draw in domestic league last six games. I can't favorite with Bayern Munich win on next match because Barcelona have consistent win last five games in a row.
