As far as I can see the pundit who is commentating on the game dictates whether it's a likely foul or not and whether the media pick up on it and more surprisingly whether even our own fans believe it was a foul.
It was the same with ederson being fouled by Arnautovic last week.. He barged Ederson off the ball, came on here and people were talking the same as the pundit, "should have been stronger"
Don't believe the pundits and commentators at all, we know they are bias, unfortunately they set the narrative
