Sadio Mane couldn't give quite the expected performance when he played as a centre-forward. And it is totally normal as well. Because he isn't naturally a centre-forward. Besides he has much more different characteristics than Lewandowski. The thing Bayern Munich need now is to sign a complete forward like Lewandowski. This can help them seriously about pulling themselves together.
Choupo-Moting tried to do some good things there but it wasn't enough unfortunately. Bayern Munich need a more reliable striker immediately. If Mane play as a left winger as well then their attacking line would be really strong.
Sadio Mane was expected to be a replacement for Lewandowski, but it's a shame he failed to give his best and I have to say he hasn't been able to replace Lewandowski on the front lines. At first I thought it was just a matter of time, but it turned out that until the season ended I didn't see the game I expected him to show with Bayern Munich. Bayern Munich must evaluate their front line.
If it is true that they recruited Mane to replace Lewandowski, then of course that would be a mistake. Because after all, in terms of body and style of play they are also very different, so of course if they put Mane in the same position as Lewandowski and don't change tactics then Mane will not be able to completely replace Lewandowski's role. But yes, if later Tuchel can have newer and fresher tactics and strategies by adjusting the players in the squad, then I think Bayern Munich's current squad is also good so they don't have to recruit many new players anymore.
