Kane is a very influential player in the front line and has contributed greatly to the team so far, but that doesn't mean Bayern Munich's dependence on Kane is very high and the defeat to Mainz last weekend was not solely due to Kane's absence.
But for now I think Kane can make a significant impact on Munich's performance. He is the top scorer in the Bundesliga which means if Kane was not injured and played in that match I think Munich would have had a different result. At least the match would have ended in a draw. I'm not saying Kane is Munich's only hope but I think Munich dominated Mainz in that match but unfortunately Munich couldn't create many chances. They made 13 shots but only 1 shot on target. But in the end a win is a win and I respect Mainz and I think they deserved the win and became the first team to beat Munich this season.
