I dont know what kind of Champions League game you have seen yesterday , even Kane hasnt scored a goal he worked for the other team players.
And he was also assisted the ball to Müller for the 2:1 goal they made.
For sure games in the German League are a bit easier for him to score and assists goals.
There will be for sure some games in this season that he will be not score a goal in the German League.
Sometimes its better for other players to shine then when the focus is on him.
I wonder why people would think because a star player doesn't score in particular match, makes him less reliable or undergarment, Harry Kane wasn't lucky to get a goal, but his performance was good and you don't expect him to score in every match, moreover the Copenhagen defence was so good and gave Bayern Munich a tough time, they gave them little space to create good chances and that was why they couldn't score more goals.
Well I think I understand why @ tusandii said that,because Kane had no shots, no goals nor assist, and as star player and top 9 for the club be should atleast get 1 shot however it does mean his performance was too bad cause his presence was felt in the match and after the game his rating in the game was quite impressive.
