Was never a red card and Smith should have been booked for blatant simulation trying to get a player sent off. Disgusting behaviour and abysmal officiating. Having said that though, you cannot be sticking your head against other players heads no matter what has gone on and he should have had the nouse to just rise above it and walk away as it has been obvious in the first 3 games that players are targetting him and that refs aren't protecting him. It is going to be the same all season so hopefully Silva will have a wise word in his shell like so that it doesnt happen again.
2 Red cards out of 3 games for practically nothing. These incompetent cowardly refs seem to be getting worse every season.
Rise above it Richarlison and just do your thing. Smiling and scoring is far more satisfying than getting sent off.
