Players are not allowed to show emotion anymore

This is getting out of hand. The FA are looking to investigate Haaland after he reacted to that awful decision yesterday. He only tweeted "wtf" as well. Didn't go on a mad cry baby rant like Arteta did when the decision yesterday was a lot worse.

So players literally aren't allowed react/show emotion when officials make such stupid mistakes? This is such a huge problem and why this keeps happening. Referees are protected. They have zero accountability. The sport we all love literally is dying. This season has been one of the lowest seasons we have had and the officials really are ruining it once and for all.
