Also, the behaviour of the Atletico players is yet more evidence why the standard of refereeing in football is so poor. Why would anyone want to put in the time and effort to be a professional referee when being treated like that is what you get at the pinnacle of the sport?
Refereeing standards will only improve when the game's authorities start actually enforcing the idea that players respect the ref (so never). I don't like to be one of those who points to rugby as the prime example, but in this area they have got it right.
