Bayern Munich must be really sad about letting Robert Lewandowski go now. He is joining the Barcelona side very soon as the agreement between the teams has been completed. It is a happy ending for Lewandowski as well because his wish has been playing for Barcelona since their interest in him started. The issues between Lewandowski and Bayern Munich caused this to happen. Bayern Munich will lose a lot of power in the attacking side for sure as Lewandowski has scored most of their goals so far.
I don't think so, because Bayern Munich have already found the replacement they had prepared long before Lewandowski left, namely Sadio Mane. A bit of loss is possible, because Lewandowski has been playing with them for a long time. But even so they will not be long to move on from Robert Lewandowski. I'm sure of that.
I thought of Sadio Mane as Lewandowski's associate. I don't think he can replace Lewandowski. Lewandowski has been with Bayern Munich for a long time. And Lewandowski's understanding of the team's players was very good. It will take time for Mane to do that. Bayern Munich may now try to sign Ronaldo. The pairing of Mane and Ronaldo will make Bayern Munich's forwards stronger.
