Bayern will certainly pick form,but we can also assume that the absence of Lewandowski is now having effect on their team,because Lewandowski was so instrumental to the success of Bayern that they will continue to miss him at his absent.He was replaced by Mane whose impact is also now felt by Liverpool.I still think the league has not gotten anywhere yet for us to conclude that Bayern will not meet up this season,things can just change and they will start winning matches again and they will win the tittle again.
Robert Lewandowski shouldn't be an important problem for Bayern Munich, because they've got high scores without relying on Robert Lewandowski, so with Mane they should be able to adapt to new players and try to work as a team well to be able to shoot on goal and score. goals, in fact the game of football is not dominated by only one person but requires excellent teamwork.
But his contribution goes beyond one player above average
I agree teamwork is needed in a match, but I can't imagine what would happen if below average players played with solid cooperation for 2x45 minutes full time.
Although Mane came as a substitute in the Bayern Munich front line, I believe there is something that Sadio Mane cannot cover like Robert Lewandowski did when he was at Bayern Munich.
