Apart from what you mentioned that doesn't match the tactics at Bayern Munich. That's because Sadio Mane was forced to replace Lewa, even though the two players have different playing styles and positions. For me, there was a mistake at Bayer Munchen's technical director. If they wanted to replace Lewa, why did they bring in Sadio Mane, who is clearly very different from Lewa.
The problem experienced by Sadio Mane at Bayern Munich reminds me of several players who left Liverpool but found it difficult to adapt to a new club. This didn't just happen to Sadio Mane. Because it's very rare for a Liverpool player to leave, let alone leave Liverpool with a problem that will shine at his new club, but not all. But most of them didn't shine, like Coutinho, Sadio Mane, Torres, Wilnajdum, dudek and others.
I don't think Mane's performance at Bayern Munich was too bad in his first season. Sadio Mane contributed to Bayern Munich's 12 goals in 25 Bundesliga matches, isn't that a good statistic for new players who still need to adapt to the team and the strategy of their new coach?
Not all players can impress for their first season at a new club, especially if they are strikers. Last season only Lewandowski and Haaland could do it with their new teams Barcelona and Manchester City, while many other players were not as good as them. Mane is a good striker, but he needs time to adapt to the new competition, but I'm sure he will be even better in his second season.
