Although Kane can maintain his fitness as a player on the Bayern Munich team in the next two seasons, the Munich team should not be completely dependent on players like Kane even though Kane is a good player on the team. Because dependence on one player can bring disaster to the team when the player moves to another team for some reason. So Munich must maintain this so that they can be very accustomed to facing any conditions when left by their best players in the future.
Every team must have two to three attackers in the squad so that this can be utilized by the coach to rotate if necessary and Harry Kane is the main attacker and if injured then he can be replaced by another attacker. Bayern Munich will definitely find a solution to this problem and indeed the depth of the squad is quite important so that they can compete in the Bundesliga and the Champions League next season. In the next one or two seasons, Harry Kane is still a quality attacker and I am optimistic that he will be able to do his best for his team.
If i am to rank strikers of now in a list, Harry Kane is making either first or second place on the list. Harry Kane has been a key player in every team he played, he has massively contributed by giving them the top performance they need to win as a club. During his time at Tottenham in the Premier League, Kane was the best striker just of recent when Isak started becoming a class striker which he can drag ranking with Kane but i still would pick Kane over him, six years gap between both strikers that's only why Isak can do more if put together to compare.
Kane just have till next year for his contract to end, i am of high hope that Bayern will love to extend and keep him to play for a few more years, at least two years contract renewal is better since he will be clocking 34 years by the time it expires.
