Valverde's decisions have nothing to do with actual performances, only his default preferences, which are: Roberto ahead of Semedo, Vidal ahead of Alena, and Rakitic all minutes, no matter how much he sucks, untouchable, the GOAT, Valverde's goat (actual animal this time) that is. A robot could literally make the substitutions that Valverde does every game...it's like simulating a match on FIFA.
Makes you wonder what type of message this sends to our bench players and new signings...a player can't thrive in an environment like that, knowing that no matter what he does, he still won't ever make it to gala XI. Semedo and Alena deserved the full 90 tonight no question, and we probably would've won if they stayed on.
