With the signing of De Ligt and even though Bayern Munich lost Lewandowski. It feels like they are a stronger team now than they were 2 months ago. They needed better defensive players and they've now got De Ligt with a 5 year contract. In terms of attack, they've got Mane to run down the wings and create more chances.
Yes, this is what Bayern Munich need for them to be able to compete next season at a higher level. I see they are more prepared now, because some time ago it was their defense that still needed to be improved. But now with De Ligt officially joining them it is good news to strengthen their defence. Finally they won the competition in targeting players.
