I'm not condoning the elbow but zero fuss was made about
Gerrard on Welbeck or
Gerrard on Brown (though Brown is a huge cunt) when he went out of the way to miss a simple header to elbow Welbeck in the face. Gerrard got a yellow but despite being a massive violent thug off the pitch as well, gets away with no questions asked.
Foul language is massively rife in football, you'll see players mouthing expletives all the time to officials, you'll hear clearly audible disgusting (Munich, Heysel etc)
chants from the crowd. I was watching the West Ham match and Rooney was being called clearly "a fat bastard" and "granny shagger". You can hear the manager's swearing over the touchline mics (and indeed John O'Shea yell that's a fucking foul). Players swear all the time in their celebrations but I guess the trick is not to face the camera, I guess.
