It's the great unspoken truth. I'm sure his perspective is rooted in his Spanish experience where no one even denies it. Here I think it's driven also by the media and Sergio's proximity O'Telly.
Take Shrek, granny shagging, public urinating, cheating on his pregnant wife, swearing into cameras, criticizing his own England fans, cowardly stamping his way out of a major tournament. But it's that Big Bad Foreign Mario that is crazy, unprofessional, unpredictable.
Suarez gets hammered for his diving, rightly so, but Ashley Young? Or Gerrard? Or Shrek again?
Mario was hounded so badly after that questionable "stamp" his Agent talked about him having to leave the country. When he gets cold cocked with an off the ball English elbow? You'd better be able to read small print 4 pages in from the back cover to even find any coverage, forget about condemnation.
The Managers need to do something the Papers say, but when Crouch drives the lane for the Harlem Globe Potters and his British Manager says " If he got away with one then Brilliant!!" where is any media comment or questioning of the helpfulness of that attitude?
No penalty for Sergio last week? British pundits consensus? "It's his own fault, he should have gone down"
The question really isn't whether Sergio is right, the question is how can any reasonable student of the game even try to deny it?
