Lots of unknowns before this game, but I saw a nice analysis from a french youtuber: https://www.youtube.com/watch?v=B50lC_kEAys
He thinks BvB could play as 4231:
Köbel
Süle – Hummels – Schlotterbeck – Bensebaïni
Sabitzer – Özcan
Malen – Reus – Brandt
Fullkrüg
And for PSG, he as more uncertainties but could see:
Donnarumma
Hakimi – Marquinhos – Skriniar – Hernandez
WZE – Ugarte – Vitinha
Barcola – RKM – Mbappé
If you understand French, go watch the whole video, there is a lot more than this !
