In my opinion, if Harry Kane don’t get to return fully fit before their next Bundesliga game against Dortmund, that shouldn’t be a problem that much to them but should be fit for the champions league clash against Arsenal. Bayern Munich don’t look like they’re still chasing the Bundesliga trophy with Bayern Leverkusen since they’ve given them the point gap and will look almost impossible to catch up with them now. Since their most focus is on the Champions League now, they should prioritize their top players playing in the Champions League matches than the Bundesliga games. I don’t think Bayern Munich will fall out from second place on the Bundesliga standing even without their striker Harry Kane, but they can be removed from the champions league competition by Arsenal if they don’t use their full squad including their striker Harry Kane in that match.
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.
