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.
Bayern is currently very weak and with their performance, Lazio has realistic chances against them. Of course, Bayern should not be underestimated and maybe they will cause a surprise, but in the next round at the latest they will definitely lose against a slightly stronger opponent and be eliminated from the CL. That's why I don't see Tuchel and co winning any title this year.
There is so much trouble going on in Bayern Munich, the whole team lacks confidence and sometimes tactics and strategy. Tuchel had a weird line up last Bundesliga game and he let the team play in a formation that they usually don't play like that. I wonder if he is still pissed and weakens the team on purpose as he couldn't give a reasonable explanation for his decisions.
If Lazio ever has a chance against Bayern Munich, then it is now. They won't face Bayern Munich ever again in such a bad condition. But it is still a game at home and I think that even a weak Bayern Munich team has a realistic chance to turn this around.
