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.
Football is a team game, not an individual game. Harry Kane did perform well with Bayern Munich in his first season, in the Champions League he has packed 4 goals and 3 assists, it is a good contribution from a total of 12 goals that Bayern Munich has created in the Champions League. In the Bundesliga, he also scored 21 goals in the 15 matches he played. But in the group stage they do not have significant pressure, because the 3 teams in the same group with them are experiencing difficult situations. Manchester United, which is predicted to be their main competitor, is also at the bottom of the table. The real test will come after passing the round of 16 in my opinion, because in the round of 16 I still trust them.
Its going to be an interesting period when the round 16 will kick off in the UEFA champions league.The teams that are expected to go through this round to the quater final are Madrid,Bayern,Manchester City, Arsenal,Dortmund,I Include Dortmund because they are so good this season in the Champions league, finishing first in their group of death is not an easy task,so I will include them to go far past the round 16 stage.There are other teams that will push towards making the quater final,but i'm optimistic about this few I mentioned.I really can't wait for this period to come because it is through this league that the best teams in the world are known.Last season,it was Mancity,but I doubt if they will be able to defend the tittle this season.
Being in the toughest group in the Champions League this season to win the group with 11 points from 3 wins, 2 draws and 1 defeat is a good record for Borussia Dortmund. Their performance is very different in the Champions League and for the Bundesliga their performance is not very good. But to compare with other teams as you mentioned, I personally still can't do it. Not without reason, the article they became one of the teams that might be arguably inconsistent when in the Champions League.
PSV will be their opponent in the round of 16, it could be a stumbling block for them too.
