Harry Kane played in Premier League many years and is a second best scorer in history of Premier League. He faced with Manchester United many times so he has enough experience with Manchester United and understand the opponent well. Beating Manchester United can help Bayern Munich to open a gate to get a first position in this group and can complete their tasks in this group a little bit sooner.
That's what I initially thought, Harry Kane should be relied on in this fight but he didn't do it well he only scored a goal through a penalty. With one goal ahead is certainly not a good position for Bayern Munich in the second leg because Manchester United could have destroyed them at home this is clearly a loss for Munich, luckily they were in an easy group only Manchester United the strongest competitor while 2 more opponents are of course easy opponents so Munich and Manchester United still have a chance to qualify for the stage.
