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.

Harry Kane has no time to fight not quarrel, always in the right place readying for the pass that'll lead to goal. He gave Bayern Munich what they was looking for exactly since Robert Lewandoski left the club. The only thing I don't want for Bayern Munich is for them not to win the Bundesliga, they have won too much and made the Bundesliga League Competition already too boring to follow up and watch.
I haven't seen the goals he's scored for Bayern Munich during the Champions League games but I have followed the Bundesliga. Believe me, he'll score more goals in the remaining half ahead.
Bayern Munich really made a goos choice and same for Kane. Failure to move and he'll never get the chance to play for such a high Club.
If he doesn't get injured his chances are good that he will set a few new records this season with his goals, but I don't think Bayern Munich is ready for the Champions League title. Lazio won't be the hardest hurdle for them to take, but I would see Bayern Munich at a disadvantage against Real Madrid, Manchester City and Inter Milan. When I say disadvantage, it doesn't mean that they have no chance. It means that I believe they would be slightly behind. I saw a few games when they showed their bad face. But we have to be patient anyway. The break until the next round starts is too long.
