Harry Kane has had a big influence on the overall performance of Tuchel squad this season, since being brought in last summer, his presence in Bayern Munich front line can give them an easy win. It is very natural that if Harry Kane is injured, fans will feel worried, it could be difficult for Bayern Munich to win in important matches, such as facing Dormund and Arsenal in the future. Tuchel certainly needs Harry Kane more in the Champions League match, he is very experienced in stopping Arsenal, who are currently slightly favourites.
There was an opinion that Premier League players find it hard to adapt to other leagues' clubs, but that didn't seem to be the case for Kane. No doubt that he's Bayern's key player, with 31 goals and 7 assists.
The other Bayern's top scorers are: Musiala (10), Sané (
and Tel (5). So all three combined have only 23 goals, not even close to Kane's 31 goals.Can Bayern win without Kane? Sure, but he's absence would be a big blow and would make it much harder.
