The present Bayern Munich team has a lot of tactical problems right now as it has affected the form of the team, the moral to come back when they are a goal down is no longer there but looking at the chances they have in their league it would be possible for them to shift their focus on their game against Lazio since it's possible that Leverkusen will win their league since they are 10 points ahead of Bayern Munich now with few matches left to play.
Bayern Munich lost to Lazio as a result for poor performance which was seen as a wrong tactics from the coach but believing that Thomas Tuchel watch the match at home after the game he will possibly come up with a better formation that will give his team an edge against Lazio and since they are playing at home, there is a high chance of Bayern Munich winning even as they are not in their best form.
When you look at how they are playing at the moment, it is not just that they are having a bad time. Their game lacks quality, they lack focus and precision. There is no dedication like they usually play. I can't remember when I saw Bayern Munich perform so badly for such an extended period of time. They have often had a game or two where they weren't exactly on point, but usually still won those games. But this time it looks differently. They have made some huge mistakes in the Bundesliga against Freiburg and I am pretty sure that Lazio would punish such a performance if they can't level up their game until tomorrow.
The biggest bummer for them would be if they concede an early goal as that would bring a lot of chaos into the team right from the start during that game. Normally they have tremendous quality when it's needed for a comeback, but that's not how the team works at the moment. It is more of a blame game and Tuchel is actually the biggest critic against his own team. It is sometimes funny how he makes decisions only to then say that the players messed it up. We may see the first big surprise this Champions League season.
