What does Dalot has anything to do with Darwin? Both got yellow for the same reason? As for Dalot, it was an useless red card, 93 minutes out of 94 minutes. It has nothing to do with Nunez or LFC but it's all between Dalot and Oliver. I am assuming Oliver did not like something he probably said to him.
Darwin committed a foul, yelled at the ref, got a yellow, then continue to beak at the ref and sarcastically clap. He got a single yellow.
Salah was pissed and gesticulated wildly similar to how Dalot did and then kicked the ball away. He did not receive a yellow.
Dalot was pissed off threw his arms twice and was walking away from the official and received two yellows in less than 10 seconds.
Throughout the game Oliver had not been consistently calling players for dissent and the he handed the same player two dissent yellows within seconds of each other.
Yes it's meaningless, but it still means Dalot misses a game. Oliver should absolutely be stood down for it because it wasn't a reasonable response to anything on the pitch except as a way to make himself the center of attention.
