Bayern isn't a potato club that often missteps, they know what they did. Mane has 2 skills that Lewandowski hasn't. So, by selling Lewa and getting Mane, Bayern shows us how effective that club is on the market. I am still curious who is behind the talent search. this step must follow another club like Liverpool self. Bayern did great for this session by recruiting players from outside Bundesliga.
On the other hand they also seem to be regenerating players in this regard because in terms of age it is clear that Mane is younger than Lewandowski which makes this even better for Bayern in the next few seasons.
The arrival of Mane is one thing that is quite good for them and for their defense they also get De Ligt who will clearly strengthen their defense so it is very difficult for other teams to destroy Bayern's dominance this season.
