Yes, of course Kane also needs adjustments again to optimize his performance if injured. Because in any case, he still has to be more careful so that his injury does not recur. This is homework for all football players, because injury is the enemy of every player. Harry Kane's struggle to be able to lift the trophy with Bayern Munich is very big, especially with the failure last season, so he wants this season to be truly successful. And it cannot be denied, Kane is still the main player and without Kane, Bayern Munich's performance has indeed dropped quite a bit in recent matches.
Kane at his age now, will no longer need to chase as many goals as possible. He needs his best contributions for his team in a long season, and it means if he can help the team getting as many points as possible, it's best.
Like he can score one goal every match, or something similar but less than one goal each match, it's still very important contribution from him if each goal is decisive winning goal for the team. That will be enough for Kane to win Bundesliga title with Bayern Munich in this season, after missing it last season. In Champions League, Bayern Munich are one of most traditionally successful club and they are one of best candidates to win it in this season too. Bundesliga is a more possible title to win for Kane, Champions League is more competitive, and he will need massive luck together with his own effort to win it.
Bayern Munich and Kompany will need to use Kane very cleverly to avoid his exhaustion or injury in most important weeks of season.
