I disagree with you mate on this, cause should Bayern lose on this very game to Barcelona then they probably be giving inter Milan a hedge over them in the group, as inter may win Viktoria plzen and move to 10 points up and go ahead to find a win or draw with Barcelona in their next game and this may threaten Bayern Munich position of finishing first in the group.
Bayern Munich is safe if this match loses to Barcelona though. The goal difference is quite far and I think Barcelona have realized that their condition of focusing on the Champions League this time is not very favorable. Moreover, there is Inter and not only Bayern Munich, making it difficult for Barcelona to get tickets to qualify. They just need to focus on La Liga for now.
inter milan already led 1-0 where the hosts took the lead through a goal scored by Mkhitaryan in the 35th minute. I think Intermilan will close this match with a big win because there is still a second half. So if Inter Milan has locked the win against Viktoria Plzen, then Barcelona chances of qualifying for the next round have been buried and the Barcelona vs Bayern Munich match is a match that will not change any results for both teams because even if Barcelona win points they will not be able to catch points from Inter Milan.
