Bayern Munich of last season I think is the weakest team of the club that's been seen in over a decade ago and the earlier they do something reinforcement the better for the club.
They need an in form and complete striker and also better defender than Upamencao. Harry Kane surely is the best player to fill in the striking role and also the best that'll positively effect a change in the attacking line of the club. It rumoured that Bayern Munich is doing everything possible to bring him to Allianz Arena and that I think will be great news for the club's fans if the deal is finally signed
Apart from that, there are also several Bayern Munich players who have reportedly left this season, so Bayern Munich must do a bigger job in this season's transfer window. Cancelo was officially not made permanent by Bayern Munich in this transfer window, so Tuchel will probably think about this gap as best he can. So there are many things that Tuchel will do in strengthening the squad for next season, even Bayern Munich is also associated with De Jong.
If you look at their competing teams in the bundesliga, of course they will be stronger next season, be it Leverkusen or Dortmund. Leverkusen had a good rally in the hands of Xabi Alonso so bayern munich will have to watch out for another team's comeback to break their trend in Bundelisga. For Harry Kane it looks like he will have a hard time in signing this as Tottenham have fetched him a hefty price tag and Bayern Munich should be able to offer as close to Tottenham as they want if they really want Harry Kane for next season.
