Tuchel will have the same discussions right away from last season because Bayern showed to have the same issues again: wasting lots of opportunities and quite a few defensive mistakes, where Leipzig was effective to score. Upamecano was close to being sent off as well due to a tactical fould, where he got away.
Kane played today but only about half an hour, so he couldn't really achieve anything. Bayern's players resignated already, when Kane came in, so Kane didn't get any suitable assists from his collegues.
Hopefully, we are up for an interesting season, where Bayern will have problems to pull away too easily from Dortmund and Leipzig.
