08-09 Champions League Bayern VS Barcelona, who has a better chance to advance to the semi-finals?

I think it's Barcelona. First of all, Bayern's defense is not good this season, while Barcelona's attack is super strong, and Bayern is very likely to make mistakes in the defense line. Secondly, Bayern's attack is too dependent on Ribelli, and Ribelli is likely to be clamped down by Alves and yaya toure. Once Ribelli is frozen, Bayern's attack will be greatly reduced. In addition, after Donovan returned to the United States, Bayern only had three strikers, and the repeated impact of the League and the Champions League would cause physical problems for the three strikers. Moreover, Bayern's reserve forces are weak and cannot cope with multi-line operations.
