I wouldn't be so sure, Lewandoski is so demotivated, also I don't like the style of playing of Julian Nagelsmann. Let'see what will happen, but I think that the next year will be the year of other team Like Borussia Dortmund,
Bayern can't stay at the top forever.
It seems that Lewandowski will still be sold to Barcelona (at least there was information that the clubs are already very close in understanding the financial conditions), but Mane will come in his place, there is already a verbal agreement with the player, and Liverpool will receive the money that Bayern will receive for Lewandowski. Bayern will definitely not be weaker next season while newcomers Dortmund have yet to prove their strength.
