I'm looking forward to the Barcelona-Bayern game with great interest, not because I believe in Barcelona's comeback, but because it's interesting to see how Bayern will play this game without the motivation to win. I think even in such conditions they can win big.
I don't think Bayern Munich doesn't have any motivation to win against Barcelona, if they lose in this match, Barcelona has a chance to qualify for the next round since Barcelona will play against weak club while Inter Milan need to face Bayern Munich. If Barcelona losing this match, it's a sweet revenge by Bayern Munich since there's no chance for Barcelona to qualify for the next round. Lewandowski will sad here lol.
Until the last sentence, I could not understand what the "sweet revenge" would be for

Barcelona is a stable supplier of points for Bayern and if the management of Bayern chose which to let Inter or Barcelona in the playoffs, then I'm sure they would choose Barcelona as a victory over them seems more reliable than over Inter. But the situation with Lewandowski completely changes the case, I agree. Bayern go further, and Lewandowski without Bayern goes only to the Europa League - sounds very mocking!
Lewandowski is one of the best players in the world, Lewandowski deserves a better club than Barcelona. It would be really sad for Lewandowski if Barcelona were to be eliminated from the Champions League altogether. If Barcelona are lucky enough to go through to the next round, they will be well on their way.
