I believe that Harry Kane has a really big role in Bayern Munich's being shown as the second biggest favourite for the Champions League title by bookmakers.
Because his contribution level in his first year there is just incredible.
He is a goal machine literally everywhere right now. He has been making contribution in two ways in the Champions League - goals and assists both. As long as he is in form like this Bayern Munich always have a chance for playing at least in the finale. But the team performance should stay solid in the meantime. Because they weren't reliable in the group stage as much as they have been in the Bundesliga. 
Kane is a goal machine since his time in Tottenham, his effort is not considered useful since the team is not winning trophy, even at that he is a recognized player because of his individual achievements related to goal scoring both in Tottenham and in the national team.Because his contribution level in his first year there is just incredible.

His coming to Bayern Munich is like a dream come true for him as a player because he is a world class player that need trophies to be recognized globally, and I believe that he can win trophies in Bayern Munich. His goal contribution to Bayern Munich is a good effort for him, and it clearly shows that he can help Bayern Munich win so many trophies, and also help the team to gain back their strength in the Europe because Bayern Munich was a very good team back then in the Champions League, and now Harry Kane will make them a good team again because he will surely score more goals.
