de Ligt was awesome this year. He looked significantly better with Bayern than when he did with Juve... and I think a lot of that had to do with his fitness level, which improved once joining Bayern.
If you had to rank the best/most consistent performers for Bayern this season, he'd have to be top 3.
I wouldnt be shocked to see him spend 10 years there and go down as a club legend. It just works and fits. And if somehow Kimmich were to leave sometime in the next 4-5 years, I'd bet on de Ligt being the one who would take the captain's band from him.
It sucks it didnt work out with Juve, but that happens.
