Trincao played til minute 67. Pedri and Mingueza full 90 mins. Dest still coming off injury came on to play 20 minutes. Only Puig not on. Who else are we missing?
Edit: Ah yes, there is Ilaix as well.
Did we need Lenglet, Griezmann or Busquets this game at that point? Was there any reason to sub them on? No, there wasn't.
Could we rest Pedri who has started playing like exausted Rakitic circa. 2019? Yes we could.
Could we rest Messi after the 3-0? Yes we could.
Can Trincao at his age play the full 90? Yes he can.
There is simply no logical reasoning behind Koeman's selections and it shows, because the team is dead tired and he mostly insists to not even use his 5 subs most of the time.
