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.
