For Barcelona vs Inter game will not be that easy as Inter can be happy also with a draw in this game so that can make things pretty difficult.
Bayern Munich played well in the UCL but the games in their League were poor. They are in fifth place. Four games without a win. In the UCL I think Bayern Munich are the favourites to qualify for the knockout phase. Inter and Barca will probably be scrambling for second place. When compared to actually I am more sure if Barcelona win. Barcelona is pretty good in the league, while Inter is unstable. The second game certainly competed seriously for second place. The defeat to Bayern Munich is not the benchmark for Barcelona failing to qualify for the knockout Phase, there are still a few games so there are still many opportunities to have.
Bayern Munich may not have achieved the results they wanted in the Bundesliga, but things are still going their way in UCL. I think we will see Barça and Inter fighting for second place. Bayern Munich will not lose the lead to anyone. In defeats in the league, the leading team of the match was Bayern Munich, which found more positions. We can say that they were a little unlucky in these league defeats.
Bayern Munich's victory over Barcelona became a turning point where they were more trusted to become group winners. However, there is still the second leg, where the team that now lost in the first leg will try to retaliate in the second leg. The results in the second leg will be more visible who will have more chances. Now, Bayern Munich is the leader in the group, but things can still change in the second match. I put 2 teams actually, namely Bayern Munich and Barcelona.
