If we look at the statistics last year, Mane was a player who fell short of expectations in the Bundesliga. He played a game far from the scoring habit that Lewandowski had left. He played in 25 games and the thought of selling him and buying Harry Kane seems like a logical decision on paper as it was not considered enough.
In my humble opinion, it would be much better for Bayern Munich if Sadio Mane and Harry Kane formed an attacking link, but if there is a question of choosing between these two players, then I think Kane would be a much better option. But I still think that the management of Bayern Munich should still give a chance to prove themselves this season.
