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.
There is no hope about Barcelona anymore to qualify for the next round, that is because the percentage of chances has been very low if Inter win the home match against Viktoria Plzen. At the moment Inter are leading the game with a 2 goal advantage from the first half and I think they are safe enough to slow down the tempo of the game.
Even if Barcelona win from Bayern Munich then it will only make them 3 points away from Inter. So Barcelona just need to make the most of this game to qualify for the Europa League which I think is more likely for them this season. Barcelona's challenge was too much, but their failure was by no means surprising.
