Yes, I admit that Lazio is indeed in a positive trend after beating Munich at home and of course it was a little painful for Munich and also reduced the mentality of the players because no one expected that Munich would lose early considering Munich's ability and experience in UCL but were defeated by a team that I don't have much experience. And I think currently Lazio is preparing to face Munich at away and using a defensive strategy, but it looks like this won't be easy to do because Munich will definitely avenge their previous defeat because the aggregate created by Lazio is only one so Munich still has the opportunity to create an aggregate of more than 1 to bring Munich through to the next round, this is if Munich no longer makes mistakes like match before.
What happened in the Bundesliga put the Bayern team in serious trouble and this will have an impact on the team's performance so Lazio can take advantage of this in the first leg to steal important points at home to Bayern.
The possibility of a second leg in the future is still wide open for Bayern, but I am quite pessimistic after seeing Bayern's performance at the moment, they are really not at their best and also the second leg will be played at home to Lazio so this will be very difficult. for Bayern.
After all, the second leg later Bayern Munich will play at home which will be played at the Allianz Arena, so Bayern Munich still has a chance to be able to turn things around and then qualify for the quarter finals. Because ya, the aggregate victory with only a score of 1-0 is clearly still completely not safe for Lazio although of course, Lazio will maintain the aggregate victory but if Bayern Munich continues to attack in the end Lazio will concede too.
Moreover, if for example Lazio still plays attacking in the second leg later, then it will make Lazio have a gap in thier defense, so it is still possible for Bayern Munich to succeed in making a goal in the second leg later at the Allianz Arena. Because anyway, it is clear that Bayern Munich still has better quality, it's just that Bayern Munich is experiencing a lot of pressure this season so that it has a bad impact on their results and performance at this moment.
