Saying about Kane, talent is not enough because he was considered does not have potential to become a star player when he was young. It means he actually was very ambitious about his career, confident about himself and also very professional in training, playing to achieve what he has now.
Now, we can say he is a talented player but he has more, experience which is very important in big matches and big competitions. It is a biggest value from Harry Kane that Bayern Munich saw and bought him from Tottenham Hotspur. He can score goals, many goals like or even more than Lewandowski but he provides more than goals, he can make key passes and assists which Lewandowksi can not do well like Kane.
It helps Bayern operation in matches become more unpredictable and consequently more dangerous for opponents.
If you are doubting Kane's skill by any chance @AHOYBRAUSE then what you are thinking is absurd. He was someone who put up a fight with Haaland in the Premier League in the top scoring. He is the highest scorer in all of Europe's top leagues combined. The Premier League is literally the toughest league in the world and the most indeed. It is no surprise he has achieved what he has achieved with Bayern Munich. As for him playing in Italy, I think he would be successful there as well. Strong defense or not, a world class striker like Kane finds his way around the field.
Look at Lukaku and Ronaldo, both did pretty good in Italy despite not playing there. I know Serie A is super defensive but those were not the problem for Ronaldo and Lukaku before he went to Chelsea. I believe Kane won’t face a problem either. He holds the capability to play in every league I believe.
Those who doubt Kane's quality don't really understand football, he is still capable of being a goal-hungry striker even though he plays at Tottenham, which is always unable to compete with other big clubs in the title race. So far, Kane has had difficulty lifting trophies because he is in a squad that does not have a winning mentality, their performances always fail to maintain their best performance and they have difficulty winning the title.
Kane appearance did not change after joining Bayern Munich, he was able to maintain his best performance and became the temporary top scorer in the Bundesliga. He managed to conquer the Bundesliga in his first season, he was also able to adapt well since being in the Bayern Munich squad and managed to secure his position in the main squad.
