Even in his first season with Bayern Munich he was already at the top of the Bundesliga top scorer list. It must be admitted that he was able to adapt well to a new environment and even though he was still new, he was enough to meet most people's expectations regarding his performance which still showed stable numbers for an experienced striker.
He has answered all doubts by becoming the Bundesliga's top scorer with 21 goals. 30 years old with 15 Bundesliga games is incredible. I think the Bundesliga also has similar quality to the EPL. But it's the EPL that I consider the most competitive league so far. But it's also possible that Kane gets better support at Bayern Munich. So Kane seems to perform more perfectly in the Bundesliga than when appearing in the EPL. With a price of €100 million I think Munich is not a loss for playing time until the age of 33-34 years.
