^ That's what UEFA are hiding behind for sure. How about they start with the obvious ones and go from there?
Seriously, it isn't hard. So many players should be charged with bringing the game into disrepute.
I don't understand why FIFA/UEFA (just like goal line technology) can't see that it's in their best interest long term to clamp down, because it's killing the game as a spectacle and killing the game's credibility.
The biggest problem though is no one is willing to look at themselves, every one passes the buck by saying "ohh but they do this, and those guys do that". Last night was an utter joke and we're going to see it again and again.
