Bayern Munich manager Julian Nagelsmann says they aim to win tonight at Camp Nou.
Bayern already have qualified for the Champions League round of 16, while Barcelona need to win for any chance of keeping their hopes of progress alive.
Nagelsmann said: “We have nothing against Barcelona, we just want to win.
“I can’t judge Lewy’s (Robert Lewandowski) performance in Barcelona, but he scores a lot of goals. We started very well, then we went through a phase in which we didn’t score many goals. We’ve done more now than last year. I think he is happy and so are we.
“We want to win, it is the first place in the group. But it’s also about winning a prestigious match. If you want to win the Champions League, you have to send signals. Tomorrow we will try to do it.”
