Especially after this game, where they got the biggest ref mistake in their favour (handball penalty not called).
Regarding this mistake, has this ref got any punishments from UEFA? I mean he didn't get help from VAR, although Barca players were desperately begging him to at least take a look. From his attitude, we can see that he was so confident about his decision at that moment although it's just plain wrong. How ridiculous this guy was!
