It's interesting indeed, because even though Bayern Munich this season will fail to win the Bundsliga trophy but yes, basically Bayern Munich still has good quality if we only compare Bayern Munich with Lazio. But yes,theresult in the first leg was a surprise because apart from losing with a score of 1-0, but in fact that Bayern Munich also had no shots on target at all in the first leg. Therefore, in the first leg it can be concluded that Bayern Munich played very badly or perhaps, Bayern Munich underestimated Lazio too much so that Bayern Munich was not in good focus in that match. So yes, with a very bad result in the first leg, then Bayern Munich should produce a better result in the second leg because Bayern Munich will also be playing at home.
It seems to me that there should be no such thing as underestimating an opponent at the Champions League playoff stage ,any team that was able to pass the group stage should by default be an opponent that is worthy of respect. Bayern simply were not ready for Lazio to play so well in defense, I think this is the main reason. But Bayern have the second leg where they will have a chance to turn things around, the difficulty for them may be, that their defense is not the best, and if Lazio can score again and try to play just as well in defense then there could be a sensation.
Bayern Munchen has shifted their full focus in the Champions League now that they don't stand a chance to win the Bundesliga this season.This makes me think that they can crush Lazio in this second leg as losing here would be a really bad move and all this season would go in vain for Bayern Munchen.I think they are more than capable of beating Lazio and I am highly confident that is exactly what is going to happen in this second leg.
