Suarez isn't really an arsehole he's just plain idiotic and can't control his temper when he's on the field. He's had two big on-field incidents involving opponents only. Ibra is an arsehole though. He will compromise the well being of his own squad and will go about disrupting a clubs environment if it means he can feed his ego. Plus Suarez ain't old.
I'd def take Suarez over Ibra. Ibra is a straight up mercenary... Suarez really does love the clubs he plays for, he shows heart and passion. He just makes some really stupid decisions.
Plus Suarez is 26, he's just getting into his prime, his best years may still be ahead of him. Ibra is 31 and starting the twilight of his career. It;s a no-brainer, imo.
There is only the small factor of the actual quality of both players to consider. Suarez is a genius and WC player. Is he worth the risk? Yes.
As for Balotelli, he is a good player, but over-rated by so many. He's not in the same league/category as Suarez; far from it in fact. Now, taking the obvious difference in quality between the two players, ask yourself the question, is Balotelli worth the risk? The answer is a resounding no.
For any of you claiming that Suarez is a racist: the dude is from Uruguay and the nickname El Negro is a very common one. They do not make a distinction between the different shades of black, so Evra is considered a Negro while Suarez in his turn is also considered a Negro by others in Uruguay.
Just to set this straight before some headless chickens draw all their conclusions based on what is hyped in the media.
Besides, the dude is a winner and will do anything possible to win and upset you during the game. If biting is necessary and he is totally provoked, he will do it. You can put all your moral issues aside when it comes to competitiveness and sport. Do not for a second believe that you are ever playing/watching a fair game, there's always some shit going on in sports. I'd rather have my players be competitive and bite someone for once than dropping on the ground with every touch they receive and fall like they have been hit by a sniper.
